Coatomer subunit beta' is a protein that in humans is encoded by the COPB2 gene.[1][2]
The Golgi coatomer complex (see MIM 601924) constitutes the coat of nonclathrin-coated vesicles and is essential for Golgi budding and vesicular trafficking. It consists of 7 protein subunits, including COPB2.[supplied by OMIM][2]
Interactions
COPB2 has been shown to interact with RGS4,[3] PRKCE[4] and COPB1.[5][6]
