Previous GeneCards Identifiers for GNAT2 Gene
Transducin is a 3-subunit guanine nucleotide-binding protein (G protein) which stimulates the coupling of rhodopsin and cGMP-phoshodiesterase during visual impulses. The transducin alpha subunits in rods and cones are encoded by separate genes. This gene encodes the alpha subunit in cones. [provided by RefSeq, Jul 2008]
GeneCards Summary for GNAT2 Gene
GNAT2 (G Protein Subunit Alpha Transducin 2) is a Protein Coding gene. Diseases associated with GNAT2 include Achromatopsia 4 and Achromatopsia. Among its related pathways are Phototransduction and G-Beta Gamma Signaling. Gene Ontology (GO) annotations related to this gene include GTP binding and obsolete signal transducer activity. An important paralog of this gene is GNAT1.
UniProtKB/Swiss-Prot Summary for GNAT2 Gene
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Transducin is an amplifier and one of the transducers of a visual impulse that performs the coupling between rhodopsin and cGMP-phosphodiesterase.
Heterotrimeric G proteins are membrane bound GTPases that are linked to 7-TM receptors. Each G protein contains an alpha-, beta- and gamma-subunit and is bound to GDP in the 'off' state. Ligand binding causes a receptor conformational change, detaching the G protein and switching it 'on'.
