Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables guanyl-nucleotide exchange factor activity. Involved in negative regulation of synapse maturation and regulation of postsynapse assembly. Acts upstream of or within retina vasculature morphogenesis in camera-type eye. Located in dendrite. Is active in glutamatergic synapse and postsynapse. Is expressed in several structures, including adipose tissue; alimentary system; genitourinary system; hemolymphoid system gland; and respiratory system. Orthologous to human ARHGEF15 (Rho guanine nucleotide exchange factor 15).
