Previous GeneCards Identifiers for GNG3 Gene
Guanine nucleotide binding proteins are heterotrimeric signal-transducing molecules consisting of alpha, beta, and gamma subunits. The gamma subunit determines the specificity of which signaling pathways will be affected by this particular complex. The protein encoded by this gene represents the gamma subunit of both inhibitory and stimulatory complexes. [provided by RefSeq, Jan 2012]
GeneCards Summary for GNG3 Gene
GNG3 (G Protein Subunit Gamma 3) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Presynaptic function of Kainate receptors. GO annotations related to this gene include GTPase activity and G-protein coupled receptor binding. An important paralog of this gene is GNG2.
UniProtKB/Swiss-Prot for GNG3 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'.
