Aliases for GNG13 Gene
External Ids for GNG13 Gene
Heterotrimeric G proteins, which consist of alpha (see MIM 139320), beta (see MIM 139380), and gamma subunits, function as signal transducers for the 7-transmembrane-helix G protein-coupled receptors. GNG13 is a gamma subunit that is expressed in taste, retinal, and neuronal tissues and plays a key role in taste transduction (Li et al., 2006 [PubMed 16473877]).[supplied by OMIM, Oct 2009]
GeneCards Summary for GNG13 Gene
GNG13 (Guanine Nucleotide Binding Protein (G Protein), Gamma 13) is a Protein Coding gene. Among its related pathways are PI3K-Akt signaling pathway and Ras signaling pathway. GO annotations related to this gene include signal transducer activity.
UniProtKB/Swiss-Prot for GNG13 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-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; in addition, some Gbetagamma subunits have active functions. Gbetagamma coupled to H1 receptors can activate PLA2 and Gbetagamma coupled to M1 receptors can activate KIR channels.
