Function
[RAB25_HUMAN] Involved in the regulation of cell survival. Promotes invasive migration of cells in which it functions to localize and maintain integrin alpha-V/beta-1 at the tips of extending pseudopodia. Increases the rates of ovarian and breast cancers progression and aggressiveness by modulating cellular processes such as proliferation, survival and migration of epithelial tumor cells. May selectively regulate the apical recycling pathway. Together with MYO5B regulates transcytosis (By similarity).[1] [2] [RFIP2_HUMAN] A Rab11 effector protein acting in the regulation of the transport of vesicles from the endosomal recycling compartment (ERC) to the plasma membrane. Also involved in receptor-mediated endocytosis and membrane trafficking of recycling endosomes, probably originating from clathrin-coated vesicles. Binds preferentially to phosphatidylinositol 3,4,5-trisphosphate (PtdInsP3) and phosphatidic acid (PA). Required in a complex with MYO5B and RAB11 for the transport of NPC1L1 to the plasma membrane. Also acts as a regulator of cell polarity.[3] [4] [5] [6]
