RAPGEF3 Proteins and Enzymes

RAPGEF3, also known as Rap guanine nucleotide exchange factor 3, is a 104 kDa 923 amino acid protein with two shorter isoforms produced by alternative splicing. The gene is necessary for rearranging actin at cell to cell junctions. RAPGEF3 is currently being studied for its involvement with leukemia, melanoma, pancreatitis, thyroiditis, carcinoma, prostatitis and neuronitis. RAPGEF3 is linked to the chemotaxis, cell adhesion, insulin secretion, and immune system pathways where it interacts with GNAI2, GNAI1, PDE3B, RAP1A and RAP1B.
