Overview
RAB10 is a member of the Rab GTPase family, which regulates intracellular membrane trafficking. RAB10 is involved in exocytic and endocytic pathways, particularly in polarized membrane trafficking, autophagy, and lipid transport. It plays essential roles in neuronal function, including synaptic vesicle trafficking, dendrite morphogenesis, and myelin sheath formation.
Structure
RAB10 possesses the canonical Rab GTPase structure:
GTP-binding domain: GxxxxGKST motif
Switch I region: Conformational change upon GTP binding
