Summaries for GNAT1 Gene

Entrez Gene Summary for GNAT1 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 rods. This gene is also expressed in other cells, and has been implicated in bitter taste transduction in rat taste cells. Mutations in this gene result in autosomal dominant congenital stationary night blindness. Multiple alternatively spliced variants, encoding the same protein, have been identified.

GeneCards Summary for GNAT1 Gene

GNAT1 (Guanine Nucleotide Binding Protein (G Protein), Alpha Transducing Activity Polypeptide 1) is a Protein Coding gene. Diseases associated with GNAT1 include night blindness, congenital stationary, autosomal dominant 3 and autosomal dominant congenital stationary night blindness. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include GTP binding and signal transducer activity. An important paralog of this gene is GNAQ.

UniProtKB/Swiss-Prot for GNAT1 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

Tocris Summary for GNAT1 Gene

  • 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-receptor binding results in detachment of the G protein, switching it to an on state and permitting Galpha activation of second messenger signalling cascades. There are several types of Galpha proteins; Galphas and Galphai bind directly to adenylyl cyclase and stimulate or inhibit its activity, leading to an increase or decrease in cAMP levels respectively.
