The process of introducing a phosphate group on to a protein [goid 6468] [pmid 8226978] [evidence TAS]; The process of directing proteins towards a membrane using signals contained within the protein [goid 6612] [pmid 11257119] [evidence NAS]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures [goid 7010] [pmid 11257119] [evidence NAS]; Control of the spatial distribution of actin filaments; includes organizing filaments into meshworks, bundles, or other structures, as by cross-linking [goid 7015] [evidence IEA]; A series of reactions within the cell that occur as a result of a single trigger reaction or compound [goid 7242] [evidence IEA]; A process that is carried out at the cellular level which results in the formation, 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 [goid 16044] [pmid 11257119] [evidence NAS]; The directed movement of substances, either within a vesicle or in the vesicle membrane, into, out of or within a cell [goid 16192] [pmid 11257119] [evidence TAS]; The specification and formation of the polarity of a cell along its apical/basal axis [goid 35089] [evidence IEA]; Development of a photoreceptor, a sensory cell in the eye that reacts to the presence of light. They usually contain a pigment that undergoes a chemical change when light is absorbed, thus stimulating a nerve [goid 42462] [evidence IEA]; Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of an epithelial cell [goid 45197] [pmid 14676191] [evidence TAS]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of a cell-cell junction. A cell-cell junction is a specialized region of connection between two cells [goid 45216] [pmid 11257119] [evidence IMP]; The regulated release of a substance by a cell, a group of cells, or a tissue [goid 46903] [pmid 8226978] [evidence NAS]
