Small G proteins of the RAB family (see MIM 179508) function in intracellular vesicle trafficking by switching from the GTP-bound state to the GDP-bound state with the assistance of guanine nucleotide exchange factors (GEFs; see MIM 609700) and GTPase-activating proteins (GAPs). TBC1D10B functions as a GAP for several proteins of the Rab family. TBC1D10B (TBC1 Domain Family Member 10B) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and TBC/RABGAPs.
