Gnat1 - G protein subunit alpha transducin 1

Enables G-protein beta/gamma-subunit complex binding activity and GTPase activity. Acts upstream of or within several processes, including cellular response to electrical stimulus; detection of light stimulus; and eye development. Located in photoreceptor connecting cilium; photoreceptor inner segment; and photoreceptor outer segment. Is expressed in brain; photoreceptor layer outer segment; retina; and retina outer nuclear layer. Human ortholog(s) of this gene implicated in congenital stationary night blindness 1G; congenital stationary night blindness autosomal dominant 3; and night blindness. Orthologous to human GNAT1 (G protein subunit alpha transducin 1). [provided by Alliance of Genome Resources, Apr 2022]
