Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables several functions, including guanyl-nucleotide exchange factor activity; small GTPase binding activity; and transmembrane transporter binding activity. Involved in regulation of membrane depolarization and regulation of sodium ion transmembrane transport. Located in intercalated disc and nucleoplasm. Is expressed in central nervous system; retina; retina ganglion cell layer; retina inner nuclear layer; and retina outer nuclear layer. Orthologous to human RANGRF (RAN guanine nucleotide release factor).
