Biology:GAPVD1
GTPase activating protein and VPS9 domains 1, also known as GAPVD1, Gapex-5 and RME-6 is a protein which in humans is encoded by the GAPVD1 gene.[1][2]
Function
GAPVD1 is Rab GTPase guanine nucleotide exchange factor essential for activation of RAB5A during engulfment of apoptotic cells.[3] GAPVD1 is also involved in the degradation of the epidermal growth factor receptor.[4] Gapex-5 mediated activation of Rab5 has been implicated in the insulin stimulated formation of plasma membrane phosphatidylinositol-3-phosphate.[5]
Structure
Based on sequence homology, mammalian Gapex-5 has been shown to have an amino-terminal Ras GAP domain, a central polyproline (SH3 binding) region and a carboxy-terminal Rab GEF domain. The RabGEF domain has been suggested to activate Rab5[6] and Rab31.[7]
