DESCRIPTION

Also known as RIC1_HUMAN, RIC1, CIP150, KIAA1432. The RIC1-RGP1 complex acts as a guanine nucleotide exchange factor (GEF), which activates RAB6A by exchanging bound GDP for free GTP, and may thereby be required for efficient fusion of endosome-derived vesicles with the Golgi compartment (PubMed:23091056). The RIC1-RGP1 complex participates in the recycling of mannose-6-phosphate receptors (PubMed:23091056). Required for phosphorylation and localization of GJA1 (PubMed:16112082). Is a regulator of procollagen transport and secretion, and is required for correct cartilage morphogenesis and development of the craniofacial skeleton (PubMed:31932796). Forms a complex with RGP1; the interaction enhances RAB6A GTPase activity (PubMed:16112082). Interacts (via central domain) with RGP1 (PubMed:16112082). Interacts with RAB6A; the interaction is direct with a preference for RAB6A-GDP (PubMed:16112082). Interacts (via C-terminus domain) with RAB33B; the interaction is direct with a preference for RAB33B-GTP (PubMed:16112082). Interacts with GJA1 (PubMed:23091056).
