Gene: GNAT1 (G protein subunit alpha transducin 1) Homo sapiens
Symbol: GNAT1
Name: G protein subunit alpha transducin 1
Description: Predicted to have several functions, including G-protein beta/gamma-subunit complex binding activity; acyl binding activity; and purine ribonucleoside binding activity. Involved in detection of light stimulus involved in visual perception and phototransduction, visible light. Localizes to photoreceptor inner segment and photoreceptor outer segment. Implicated in congenital stationary night blindness 1G; congenital stationary night blindness autosomal dominant 3; and night blindness.
Type: protein-coding
RefSeq Status: REVIEWED
