    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:0060333    interferon-gamma-mediated signaling pathway    A series of molecular signals initiated by the binding of interferon-gamma to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription. Interferon gamma is the only member of the type II interferon found so far.
    GO:0002503    peptide antigen assembly with MHC class II protein complex    The binding of a peptide to the antigen binding groove of an MHC class II protein complex.
    GO:0002506    polysaccharide assembly with MHC class II protein complex    The binding of a polysaccharide to the antigen binding groove of an MHC class II protein complex.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0012507    ER to Golgi transport vesicle membrane    The lipid bilayer surrounding a vesicle transporting substances from the endoplasmic reticulum to the Golgi.
    GO:0005794    Golgi apparatus    A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.
    GO:0000139    Golgi membrane    The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
    GO:0042613    MHC class II protein complex    A transmembrane protein complex composed of an MHC class II alpha and MHC class II beta chain, and with or without a bound peptide or polysaccharide antigen.
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    GO:0030669    clathrin-coated endocytic vesicle membrane    The lipid bilayer surrounding a clathrin-coated endocytic vesicle.
    GO:0030666    endocytic vesicle membrane    The lipid bilayer surrounding an endocytic vesicle.
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0005789    endoplasmic reticulum membrane    The lipid bilayer surrounding the endoplasmic reticulum.
    GO:0005768    endosome    A vacuole to which materials ingested by endocytosis are delivered.
    GO:0010008    endosome membrane    The lipid bilayer surrounding an endosome.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    GO:0071556    integral component of lumenal side of endoplasmic reticulum membrane    The component of the endoplasmic reticulum membrane consisting of the gene products that penetrate only the lumenal side of the membrane.
    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:0005764    lysosome    A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions.
    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.
    GO:0032588    trans-Golgi network membrane    The lipid bilayer surrounding any of the compartments that make up the trans-Golgi network.

molecular function
    GO:0002020    protease binding    Interacting selectively and non-covalently with any protease or peptidase.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0019911    structural constituent of myelin sheath    The action of a molecule that contributes to the structural integrity of the myelin sheath of a nerve.
biological process
    GO:0007568    aging    A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700).
    GO:0008366    axon ensheathment    Any process in which the axon of a neuron is insulated, and that insulation maintained, thereby preventing dispersion of the electrical signal.
    GO:0007417    central nervous system development    The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.
    GO:0007268    chemical synaptic transmission    The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.
    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:0061024    membrane organization    A process which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins.
    GO:0042552    myelination    The process in which myelin sheaths are formed and maintained around neurons. Oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system wrap axons with compact layers of their plasma membrane. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.
    GO:0050771    negative regulation of axonogenesis    Any process that stops, prevents, or reduces the frequency, rate or extent of axonogenesis.
    GO:0070542    response to fatty acid    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a fatty acid stimulus.
    GO:0046689    response to mercury ion    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a mercury ion stimulus.
    GO:0032570    response to progesterone    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a progesterone stimulus.
    GO:0009636    response to toxic substance    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a toxic stimulus.
    GO:0034612    response to tumor necrosis factor    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a tumor necrosis factor stimulus.
    GO:0021762    substantia nigra development    The progression of the substantia nigra over time from its initial formation until its mature state. The substantia nigra is the layer of gray substance that separates the posterior parts of the cerebral peduncles (tegmentum mesencephali) from the anterior parts; it normally includes a posterior compact part with many pigmented cells (pars compacta) and an anterior reticular part whose cells contain little pigment (pars reticularis).
cellular component
    GO:0071944    cell periphery    The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.
    GO:0042995    cell projection    A prolongation or process extending from a cell, e.g. a flagellum or axon.
    GO:0043218    compact myelin    The portion of the myelin sheath in which layers of cell membrane are tightly juxtaposed, completely excluding cytoplasm. The juxtaposed cytoplasmic surfaces form the major dense line, while the juxtaposed extracellular surfaces form the interperiod line visible in electron micrographs.
    GO:0033269    internode region of axon    An axon part that is located between the nodes of Ranvier and surrounded by compact myelin sheath.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0043209    myelin sheath    An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system.
    GO:0043025    neuronal cell body    The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
    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.
