Genes affected

RIC1 (HGNC:17686): (RIC1 homolog, RAB6A GEF complex partner 1) Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in several processes, including positive regulation of GTPase activity; regulation of extracellular matrix constituent secretion; and retrograde transport, endosome to Golgi. Located in cytosol and membrane. Part of Ric1-Rgp1 guanyl-nucleotide exchange factor complex. [provided by Alliance of Genome Resources, Apr 2022]
