Descriptions
CHMP2A is a core component of the endosomal sorting required for transport complex III (ESCRT-III), which is involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. Removing 42 amino acids from the C-terminal of the protein unmasks a common ability to associate with endosomal membranes and assemble into large polymeric complexes, and the C-terminal sequences are also important for interaction of ESCRT-III protein with VPS4. Thus, ESCRT-III proteins cycle between a closed state and an activated open state is under control of sequences at the C-terminus and associated factors.

13 GO annotations of cellular component
| Name | Definition |
|---|---|
| adherens junction | A cell-cell junction composed of the epithelial cadherin-catenin complex. The epithelial cadherins, or E-cadherins, of each interacting cell extend through the plasma membrane into the extracellular space and bind to each other. The E-cadherins bind to catenins on the cytoplasmic side of the membrane, where the E-cadherin-catenin complex binds to cytoskeletal components and regulatory and signaling molecules. |
| axon | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
| clathrin-coated pit | A part of the endomembrane system in the form of an invagination of a membrane upon which a clathrin coat forms, and that can be converted by vesicle budding into a clathrin-coated vesicle. Coated pits form on the plasma membrane, where they are involved in receptor-mediated selective transport of many proteins and other macromolecules across the cell membrane, in the trans-Golgi network, and on some endosomes. |
| clathrin-coated vesicle | A vesicle with a coat formed of clathrin connected to the membrane via one of the clathrin adaptor complexes. |
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytoplasmic vesicle membrane | The lipid bilayer surrounding a cytoplasmic vesicle. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| dendrite | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| endosome | A vacuole to which materials ingested by endocytosis are delivered. |
| growth cone | The migrating motile tip of a growing neuron projection, where actin accumulates, and the actin cytoskeleton is the most dynamic. |
| neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| 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. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
8 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| metal ion binding | Binding to a metal ion. |

| protein serine/threonine kinase activity | Catalysis of the reactions |
| protein serine/threonine/tyrosine kinase activity | Catalysis of the reactions |
| protein tyrosine kinase activity | Catalysis of the reaction |
| WW domain binding | Binding to a WW domain of a protein, a small module composed of 40 amino acids and plays a role in mediating protein-protein interactions via proline-rich regions. |
6 GO annotations of biological process
| Name | Definition |
|---|---|
| endocytosis | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a part of the plasma membrane to form a new membrane-bounded vesicle. |
| negative regulation of epidermal growth factor receptor signaling pathway | Any process that stops, prevents, or reduces the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity. |
| phosphorylation | The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. |
| regulation of keratinocyte differentiation | Any process that modulates the frequency, rate or extent of keratinocyte differentiation. |
| signal transduction | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. |
| spermatid development | The process whose specific outcome is the progression of a spermatid over time, from its formation to the mature structure. |
