RAP1A (Ras-related protein Rap-1A) is an enzyme. In the public catalogues the evidence so far is association rather than a proven role. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Counteracts the mitogenic function of Ras, at least partly because it can interact with Ras GAPs and RAF in a competitive manner. Together with ITGB1BP1, regulates KRIT1 localisation to microtubules and membranes. Plays a role in nerve growth factor (NGF)-induced neurite outgrowth. Plays a role in the regulation of embryonic blood vessel formation. Involved in the establishment of basal endothelial barrier function. Facilitates the progressive accumulation of CDH1 at mature desmosome junctions via cAMP-dependent signalling and its interaction with PKP3. Location: Cell membrane; Cytoplasm; Cytoplasm, perinuclear region; Cell junction (UniProt). Locus 1p13.2 (HGNC).
