Previous GeneCards Identifiers for GNGT2 Gene
Phototransduction in rod and cone photoreceptors is regulated by groups of signaling proteins. The encoded protein is thought to play a crucial role in cone phototransduction. It belongs to the G protein gamma family and localized specifically in cones. Several transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Nov 2010]
GeneCards Summary for GNGT2 Gene
GNGT2 (G Protein Subunit Gamma Transducin 2) is a Protein Coding gene. Among its related pathways are Presynaptic function of Kainate receptors and G-protein signaling G-Protein alpha-i signaling cascades. Gene Ontology (GO) annotations related to this gene include GTPase activity and obsolete signal transducer activity. An important paralog of this gene is GNG11.
UniProtKB/Swiss-Prot for GNGT2 Gene
Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
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'.
