Full name: G protein subunit alpha transducin 2

Gene type: protein coding

RefSeq status: VALIDATED

Also known as: Gnat-2; Gt-2; Hg1d; Tcalpha

Summary: Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Acts upstream of or within detection of light stimulus involved in visual perception; phototransduction; and retinal cone cell development. Predicted to be located in plasma membrane. Predicted to be part of heterotrimeric G-protein complex. Predicted to be active in photoreceptor inner segment and photoreceptor outer segment. Is expressed in early conceptus; primary oocyte; retina; retina outer nuclear layer; and secondary oocyte. Used to study achromatopsia 4. Human ortholog(s) of this gene implicated in achromatopsia 4 and color blindness. Orthologous to human GNAT2 (G protein subunit alpha transducin 2).
