Gene: TBC1D20 (TBC1 domain family member 20) Homo sapiens
Symbol: TBC1D20
Name: TBC1 domain family member 20
CRRD ID: 1346411
Description: Exhibits GTPase activator activity and Rab GTPase binding activity. Involved in several processes, including COPII-coated vesicle cargo loading; positive regulation of ER to Golgi vesicle-mediated transport; and positive regulation of viral process. Localizes to several cellular components, including endoplasmic reticulum membrane; integral component of Golgi membrane; and nuclear membrane. Implicated in Warburg micro syndrome 4.
Type: protein-coding
RefSeq Status: REVIEWED
