RAB6A-GEF complex partner protein 2 (RGP1)

The RIC1-RGP1 complex functions as a guanine nucleotide exchange factor (GEF), which activates RAB6A by exchanging bound GDP for free GTP and may thereby required for efficient fusion of endosome-derived vesicles with the Golgi compartment. The RIC1- RGP1 complex participates in the recycling of mannose-6-phosphate receptors.
