DESCRIPTION
Also known as RAP2A_MOUSE, Rap2a. Small GTP-binding protein which cycles between a GDP-bound inactive and a GTP-bound active form. In its active form interacts with and regulates several effectors including MAP4K4, MINK1 and TNIK. Part of a signaling complex composed of NEDD4, RAP2A and TNIK which regulates neuronal dendrite extension and arborization during development. More generally, it is part of several signaling cascades and may regulate cytoskeletal rearrangements, cell migration, cell adhesion and cell spreading. Interacts with PLCE1. Interacts with ARHGAP29, SGSM1, SGSM2 and SGSM3. Interacts (GTP-bound form preferentially) with MAP4K4. Interacts with MINK1. Interacts with cytoskeletal actin (By similarity). Interacts (GTP-bound form) with RUNDC3A. Interacts (GTP-bound form preferentially) with TNIK (via the CNH domain); the interaction is direct and recruits RAP2A to the E3 ubiquitin ligase NEDD4. Interacts with RGS14; the interaction is GTP-dependent.
