Descriptions

ACAP1 (ArfGAP with coiled-coil, ankyrin repeat, and PH domains protein 1) is an ARF6 GAP that acts as a key component of a defined clathrin complex for endocytic recycling. A flexible linker region between the GAP and ANK domains acts to obstruct cargo binding, with a key residue within this region (Ser-554) regulating this obstruction. The excision of the linker region results in promoting cargo binding and integrin recycling.

1 GO annotations of biological process

Name Definition
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.
