DESCRIPTION

Also known as GNA13_MOUSE, Gna13, Gna-13. Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems (PubMed:21212405, PubMed:19151758, PubMed:16388592). Activates effector molecule RhoA by binding and activating RhoGEFs (ARHGEF1/p115RhoGEF, ARHGEF11/PDZ-RhoGEF and ARHGEF12/LARG) (PubMed:16388592). GNA13-dependent Rho signaling subsequently regulates transcription factor AP-1 (activating protein-1) (PubMed:19151758, PubMed:21212405). Promotes tumor cell invasion and metastasis by activating Rho/ROCK signaling pathway (By similarity). Inhibits CDH1-mediated cell adhesion in process independent from Rho activation (By similarity). G proteins are composed of 3 units; alpha, beta and gamma (PubMed:16388592). The alpha chain contains the guanine nucleotide binding site (PubMed:16388592). Interacts with UBXD5 (By similarity). Interacts with HAX1 (By similarity). Interacts (in GTP-bound form) with PPP5C (via TPR repeats); activates PPP5C phosphatase activity and translocates PPP5C to the cell membrane (By similarity). Interacts with RGS22 (By similarity). Interacts (in GTP-bound form) with ARHGEF1 (PubMed:16388592). Interacts (in GTP-bound form) with ARHGEF11 (via RGS domain) (PubMed:18940608). Interacts (in GTP-bound form) with ARHGEF12 (via RGS domain) (PubMed:16388592). Interacts with CTNND1 (PubMed:15240885). Interacts with GAS2L2 (PubMed:23994616).
