Gnat1 - G protein subunit alpha transducin 1

Enables GTP binding activity. Involved in several processes, including detection of chemical stimulus involved in sensory perception of bitter taste; positive regulation of cyclic-nucleotide phosphodiesterase activity; and rhodopsin mediated signaling pathway. Located in several cellular components, including apical plasma membrane; photoreceptor inner segment; and photoreceptor outer segment. Part of heterotrimeric G-protein complex. 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]
