| | GO:0005509 | | calcium ion binding | | Interacting selectively and non-covalently with calcium ions (Ca2+). |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |

| biological process |
|---|
| | GO:0006888 | | ER to Golgi vesicle-mediated transport | | The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi. |
| | 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:0030036 | | actin cytoskeleton organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins. |
| | GO:0051693 | | actin filament capping | | The binding of a protein or protein complex to the end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits. |
| | GO:0007015 | | actin filament organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking. |
| | GO:0007411 | | axon guidance | | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. |
| | GO:0030097 | | hemopoiesis | | The process whose specific outcome is the progression of the myeloid and lymphoid derived organ/tissue systems of the blood and other parts of the body over time, from formation to the mature structure. The site of hemopoiesis is variable during development, but occurs primarily in bone marrow or kidney in many adult vertebrates. |
| | GO:0002260 | | lymphocyte homeostasis | | The process of regulating the proliferation and elimination of lymphocytes such that the total number of lymphocytes within a whole or part of an organism is stable over time in the absence of an outside stimulus. |
| | GO:0007009 | | plasma membrane organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the plasma membrane. |
| | GO:0006779 | | porphyrin-containing compound biosynthetic process | | The chemical reactions and pathways resulting in the formation of any member of a large group of derivatives or analogs of porphyrin. Porphyrin consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0042102 | | positive regulation of T cell proliferation | | Any process that activates or increases the rate or extent of T cell proliferation. |
| | GO:0032092 | | positive regulation of protein binding | | Any process that activates or increases the frequency, rate or extent of protein binding. |
| | GO:0008360 | | regulation of cell shape | | Any process that modulates the surface configuration of a cell. |
| cellular component |
|---|
| | GO:0015629 | | actin cytoskeleton | | The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes. |
| | GO:0005938 | | cell cortex | | The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins. |
| | GO:0030863 | | cortical cytoskeleton | | The portion of the cytoskeleton that lies just beneath the plasma membrane. |
| | GO:0032437 | | cuticular plate | | A dense network of actin filaments found beneath the apical cell surface of hair cells, and into which stereocilia are inserted. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005856 | | cytoskeleton | | Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0031235 | | intrinsic component of the cytoplasmic side of the plasma membrane | | The component of a plasma membrane consisting of gene products and protein complexes that have some covalently attached part (e.g. peptide sequence or GPI anchor) which is embedded in the cytoplasmic side of the plasma membrane only. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0008091 | | spectrin | | Membrane associated dimeric protein (240 and 220 kDa) of erythrocytes. Forms a complex with ankyrin, actin and probably other components of the membrane cytoskeleton, so that there is a mesh of proteins underlying the plasma membrane, potentially restricting the lateral mobility of integral proteins. |
| | GO:0014731 | | spectrin-associated cytoskeleton | | The part of the cytoskeleton composed of spectrin, protein 4.1 and ankyrin. Spectrin-associated cytoskeleton is associated with the plasma membrane. |
