TBC1D2 (TBC1 Domain Family Member 2) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and TBC/RABGAPs. Acts as GTPase-activating protein for RAB7A. Signal effector acting as a linker between RAC1 and RAB7A, leading to RAB7A inactivation and subsequent inhibition of cadherin degradation and reduced cell-cell adhesion.
