Description

Predicted to have G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in detection of light stimulus involved in visual perception. Predicted to localize to heterotrimeric G-protein complex. Used to study achromatopsia and cone-rod dystrophy. Human ortholog(s) of this gene implicated in achromatopsia 4 and color blindness. Is expressed in pineal complex and visual system. Orthologous to several human genes including GNAT2 (G protein subunit alpha transducin 2).
