Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables GTPase regulator activity. Acts upstream of or within several processes, including angiotensin-activated signaling pathway involved in heart process; regulation of ERK5 cascade; and regulation of matrix metallopeptidase secretion. Located in extracellular space. Is expressed in several structures, including central nervous system; glans of male genital tubercle; lens; liver; and retina nuclear layer. Orthologous to human RAP1GDS1 (Rap1 GTPase-GDP dissociation stimulator 1).
