GNA13
GNA13 (Guanine nucleotide-binding protein subunit alpha-13) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Bladder & urothelial cancer, Non-Hodgkin lymphoma, Diffuse large B-cell lymphoma and 1 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signalling systems. Activates effector molecule RhoA by binding and activating RhoGEFs (ARHGEF1/p115RhoGEF, ARHGEF11/PDZ-RhoGEF and ARHGEF12/LARG). GNA13-dependent Rho signalling subsequently regulates transcription factor AP-1 (activating protein-1). Promotes tumour cell invasion and metastasis by activating RhoA/ROCK signalling pathway. Inhibits CDH1-mediated cell adhesion in a process independent from Rho activation. In lymphoid follicles, transmits P2RY8- and S1PR2-dependent signals that lead to inhibition of germinal centre (GC) B cell growth and migration outside the GC niche. Location: Cell membrane; Melanosome; Cytoplasm; Nucleus (UniProt). Locus 17q24.1 (HGNC).
