## TL;DR

NR4A3 (Nuclear receptor subfamily 4 group A member 3) is a protein that switches other genes on and off. The public catalogues list it as a biomarker and a fusion partner, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Sarcomas, Colorectal cancer, Lung cancer and 1 more.

## Summary

Transcriptional activator that binds to regulatory elements in promoter regions in a cell- and response element (target)-specific manner. Induces gene expression by binding as monomers to the NR4A1 response element (NBRE) 5'-AAAAGGTCA-3' site and as homodimers to the Nur response element (NurRE) site in the promoter of their regulated target genes. Plays a role in the regulation of proliferation, survival and differentiation of many different cell types and also in metabolism and inflammation.

CIViC holds 1 clinical evidence item and 1 assertion across 3 variants. Open Targets scores its association with cancer at 0.73 (direct and indirect evidence; datatypes genetic literature 0.61, literature 0.97, genetic association 0.33, somatic mutation 0.98, animal model 0.34).

- Biology: Transcriptional activator that binds to regulatory elements in promoter regions in a cell- and response element (target)-specific manner. Induces gene expression by binding as monomers to the NR4A1 response element (NBRE) 5'-AAAAGGTCA-3' site and as homodimers to the Nur response element (NurRE) site in the promoter of their regulated target genes. Plays a role in the regulation of proliferation, survival and differentiation of many different cell types and also in metabolism and inflammation. Mediates proliferation of vascular smooth muscle, myeloid progenitor cell and type B pancreatic cells; promotes mitogen-induced vascular smooth muscle cell proliferation through transactivation of SKP2 promoter by binding a NBRE site. Upon PDGF stimulation, stimulates vascular smooth muscle cell proliferation by regulating CCND1 and CCND2 expression. In islets, induces type B pancreatic cell proliferation through up-regulation of genes that activate cell cycle, as well as genes that cause degradation of the CDKN1A. Location: Nucleus (UniProt). Locus 9q31.1 (HGNC).
- Where found: Sarcomas: Open Targets association 0.67 with sarcoma (MONDO_0005089); Colorectal cancer: Open Targets association 0.52 with colorectal cancer (MONDO_0005575); Lung cancer: Open Targets association 0.51 with lung cancer (MONDO_0008903); Chondrosarcoma: Open Targets association 0.54 with chondrosarcoma (MONDO_0008977)

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: CIViC holds 1 clinical evidence items on its variants; UniProt disease notes describe a translocation or gene fusion involving the gene. Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
- Diseases the sources name that have no OnCo cancer page yet, so they are not linked: Acinic Cell Carcinoma.
