Predicted to enable adenylate cyclase inhibiting G protein-coupled glutamate receptor activity and protein homodimerization activity. Involved in locomotory behavior and sensory perception of light stimulus. Acts upstream of or within retina development in camera-type eye and signal transduction. Located in new growing cell tip. Is expressed in prostate gland; retina inner nuclear layer; and testis. Used to study congenital stationary night blindness 1B. Human ortholog(s) of this gene implicated in congenital stationary night blindness 1B. Orthologous to human GRM6 (glutamate metabotropic receptor 6).
