rab4a proto-oncogene protein; Ras-related protein Rab-4A (RAB4A, RAB4)

Function: - protein transport. - probably involved in vesicular traffic (putative) - early endosome-plasma membrane sorting & recycling - phosphorylated by CDC2 kinase during mitosis - interacts with RAB11FIP1, RABEP1, ZFYVE20 & RUFY1 - interacts with SGSM1, SGSM2 & SGSM3 (putative) Structure: belongs to the small GTPase superfamily, Rab family Compartment: - membrane; peripheral membrane protein - cytoplasm - generally associated with membranes - cytoplasmic when phosphorylated by CDC2
