| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0042470 | melanosome | cellular_component | A tissue-specific, membrane-bounded cytoplasmic organelle within which melanin pigments are synthesized and stored. Melanosomes are synthesized in melanocyte cells. [GOC:jl, PMID:11584301] |
| GO:0098590 | plasma membrane region | cellular_component | A membrane that is a (regional) part of the plasma membrane. [GOC:dos] |
| GO:0006887 | exocytosis | biological_process | A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle. Exocytosis can occur either by full fusion, when the vesicle collapses into the plasma membrane, or by a kiss-and-run mechanism that involves the formation of a transient contact, a pore, between a granule (for exemple of chromaffin cells) and the plasma membrane. The latter process most of the time leads to only partial secretion of the granule content. Exocytosis begins with steps that prepare vesicles for fusion with the membrane (tethering and docking) and ends when molecules are secreted from the cell. [GOC:mah, ISBN:0716731363, PMID:22323285] |
| GO:0070382 | exocytic vesicle | cellular_component | A transport vesicle that mediates transport from an intracellular compartment to the plasma membrane, and fuses with the plasma membrane to release various cargo molecules, such as proteins or hormones, by exocytosis. [GOC:kad, GOC:mah] |
| GO:0016020 | membrane | cellular_component | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
| GO:0019897 | extrinsic component of plasma membrane | cellular_component | The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region. [GOC:curators, GOC:dos] |
| GO:0031982 | vesicle | cellular_component | Any small, fluid-filled, spherical organelle enclosed by membrane. [GOC:mah, GOC:pz, GOC:vesicles] |
| GO:0043226 | organelle | cellular_component | Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. [GOC:go_curators] |
| GO:0043227 | membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. [GOC:go_curators] |
| GO:0006886 | intracellular protein transport | biological_process | The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell. [GOC:mah] |
| GO:0005488 | binding | molecular_function | The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. [GOC:ceb, GOC:mah, ISBN:0198506732] |
| GO:0110165 | cellular anatomical entity | cellular_component | A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
| GO:0031267 | small GTPase binding | molecular_function | Binding to a small monomeric GTPase. [GOC:mah, PMID:27218782] |
| GO:0005102 | signaling receptor binding | molecular_function | Binding to one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. [GOC:bf, GOC:ceb, ISBN:0198506732] |
| GO:0031253 | cell projection membrane | cellular_component | The portion of the plasma membrane surrounding a plasma membrane bounded cell surface projection. [GOC:krc, GOC:mah] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
