GNA13 (G Protein Subunit Alpha 13) is a Protein Coding gene. Diseases associated with GNA13 include Retinitis Pigmentosa 14 and Burkitt Lymphoma. Among its related pathways are G-protein signaling_RhoA regulation pathway and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include GTP binding and obsolete signal transducer activity. An important paralog of this gene is GNA12.
UniProtKB/Swiss-Prot Summary for GNA13 Gene
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems (PubMed:15240885, PubMed:16787920, PubMed:16705036, PubMed:27084452). Activates effector molecule RhoA by binding and activating RhoGEFs (ARHGEF1/p115RhoGEF, ARHGEF11/PDZ-RhoGEF and ARHGEF12/LARG) (PubMed:15240885, PubMed:12515866). GNA13-dependent Rho signaling subsequently regulates transcription factor AP-1 (activating protein-1) (By similarity). Promotes tumor cell invasion and metastasis by activating RhoA/ROCK signaling pathway (PubMed:16787920, PubMed:16705036, PubMed:27084452). Inhibits CDH1-mediated cell adhesion in process independent from Rho activation (PubMed:11976333).
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'.
