Chain A (IL2_HUMAN | P60568)

molecular function
	GO:0005088	Ras guanyl-nucleotide exchange factor activity	Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
	GO:0030246	carbohydrate binding	Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
	GO:0005125	cytokine activity	Functions to control the survival, growth, differentiation and effector function of tissues and cells.
	GO:0043208	glycosphingolipid binding	Interacting selectively and non-covalently with glycosphingolipid, a compound with residues of sphingoid and at least one monosaccharide.
	GO:0008083	growth factor activity	The function that stimulates a cell to grow or proliferate. Most growth factors have other actions besides the induction of cell growth or proliferation.
	GO:0005134	interleukin-2 receptor binding	Interacting selectively and non-covalently with the interleukin-2 receptor.
	GO:0031851	kappa-type opioid receptor binding	Interacting selectively and non-covalently with a kappa-type opioid receptor.
	GO:0019209	kinase activator activity	Binds to and increases the activity of a kinase, an enzyme which catalyzes of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
biological process
	GO:0007186	G-protein coupled receptor signaling pathway	A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
	GO:0000165	MAPK cascade	An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.
	GO:0030217	T cell differentiation	The process in which a precursor cell type acquires characteristics of a more mature T-cell. A T cell is a type of lymphocyte whose definin characteristic is the expression of a T cell receptor complex.
	GO:0002250	adaptive immune response	An immune response mediated by cells expressing specific receptors for antigen produced through a somatic diversification process, and allowing for an enhanced secondary response to subsequent exposures to the same antigen (immunological memory).
	GO:0007155	cell adhesion	The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.
	GO:0007267	cell-cell signaling	Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.
	GO:0097192	extrinsic apoptotic signaling pathway in absence of ligand	A series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with withdrawal of a ligand from a cell surface receptor, and ends when the execution phase of apoptosis is triggered.
	GO:0006955	immune response	Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
	GO:0002376	immune system process	Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
	GO:0030101	natural killer cell activation	The change in morphology and behavior of a natural killer cell in response to a cytokine, chemokine, cellular ligand, or soluble factor.
	GO:0002903	negative regulation of B cell apoptotic process	Any process that stops, prevents, or reduces the frequency, rate, or extent of B cell apoptotic process.
	GO:0043066	negative regulation of apoptotic process	Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
	GO:0045822	negative regulation of heart contraction	Any process that stops, prevents, or reduces the frequency, rate or extent of heart contraction.
	GO:0050728	negative regulation of inflammatory response	Any process that stops, prevents, or reduces the frequency, rate or extent of the inflammatory response.
	GO:0050672	negative regulation of lymphocyte proliferation	Any process that stops, prevents or reduces the rate or extent of lymphocyte proliferation.
	GO:0001933	negative regulation of protein phosphorylation	Any process that stops, prevents or reduces the rate of addition of phosphate groups to amino acids within a protein.
	GO:0030890	positive regulation of B cell proliferation	Any process that activates or increases the rate or extent of B cell proliferation.
	GO:0043547	positive regulation of GTPase activity	Any process that activates or increases the activity of a GTPase.
	GO:0045582	positive regulation of T cell differentiation	Any process that activates or increases the frequency, rate or extent of T cell differentiation.

	GO:0042104	positive regulation of activated T cell proliferation	Any process that activates or increases the rate or extent of activated T cell proliferation.
	GO:0030307	positive regulation of cell growth	Any process that activates or increases the frequency, rate, extent or direction of cell growth.
	GO:0008284	positive regulation of cell proliferation	Any process that activates or increases the rate or extent of cell proliferation.
	GO:0007204	positive regulation of cytosolic calcium ion concentration	Any process that increases the concentration of calcium ions in the cytosol.
	GO:0060999	positive regulation of dendritic spine development	Any process that increases the rate, frequency, or extent of dendritic spine development, the process whose specific outcome is the progression of the dendritic spine over time, from its formation to the mature structure.
	GO:0051024	positive regulation of immunoglobulin secretion	Any process that activates or increases the frequency, rate or extent of the regulated release of immunoglobulins from a cell.

Chain B (IL2RA_HUMAN | P01589)

molecular function
	GO:0005088	Ras guanyl-nucleotide exchange factor activity	Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
	GO:0008144	drug binding	Interacting selectively and non-covalently with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.
	GO:0019976	interleukin-2 binding	Interacting selectively and non-covalently with interleukin-2.
	GO:0004911	interleukin-2 receptor activity	Combining with interleukin-2 and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
biological process
	GO:0000165	MAPK cascade	An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.
	GO:0007219	Notch signaling pathway	A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Notch on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
	GO:0043029	T cell homeostasis	The process of regulating the proliferation and elimination of T cells such that the total number of T cells within a whole or part of an organism is stable over time in the absence of an outside stimulus.
	GO:0006924	activation-induced cell death of T cells	A T cell apoptotic process that occurs towards the end of the expansion phase following the initial activation of mature T cells by antigen and is triggered by T cell receptor stimulation and signals transmitted via various surface-expressed members of the TNF receptor family such as Fas ligand, Fas, and TNF and the p55 and p75 TNF receptors.
	GO:0006915	apoptotic process	A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
	GO:0008283	cell proliferation	The multiplication or reproduction of cells, resulting in the expansion of a cell population.
	GO:0007166	cell surface receptor signaling pathway	A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
	GO:0006955	immune response	Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
	GO:0002376	immune system process	Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
	GO:0006954	inflammatory response	The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages.
	GO:0002437	inflammatory response to antigenic stimulus	An inflammatory response to an antigenic stimulus, which can be include any number of T cell or B cell epitopes.
	GO:0038110	interleukin-2-mediated signaling pathway	A series of molecular signals initiated by the binding of interleukin-2 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
	GO:0042130	negative regulation of T cell proliferation	Any process that stops, prevents or reduces the rate or extent of T cell proliferation.
	GO:0050687	negative regulation of defense response to virus	Any process that stops, prevents or reduces the rate or extent of antiviral mechanisms, thereby facilitating viral replication.
	GO:0050777	negative regulation of immune response	Any process that stops, prevents, or reduces the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.
	GO:0050728	negative regulation of inflammatory response	Any process that stops, prevents, or reduces the frequency, rate or extent of the inflammatory response.
	GO:0050672	negative regulation of lymphocyte proliferation	Any process that stops, prevents or reduces the rate or extent of lymphocyte proliferation.
	GO:0043547	positive regulation of GTPase activity	Any process that activates or increases the activity of a GTPase.
	GO:0045582	positive regulation of T cell differentiation	Any process that activates or increases the frequency, rate or extent of T cell differentiation.
	GO:0042102	positive regulation of T cell proliferation	Any process that activates or increases the rate or extent of T cell proliferation.
	GO:0042104	positive regulation of activated T cell proliferation	Any process that activates or increases the rate or extent of activated T cell proliferation.
	GO:0046013	regulation of T cell homeostatic proliferation	Any process that modulates the frequency, rate or extent of resting T cell proliferation.
	GO:0002664	regulation of T cell tolerance induction	Any process that modulates the frequency, rate, or extent of T cell tolerance induction.
cellular component
	GO:0009986	cell surface	The external part of the cell wall and/or plasma membrane.
	GO:0009897	external side of plasma membrane	The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0005622	intracellular	The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
