The public catalogues list it as an oncogene driver and a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Bladder & urothelial cancer, Colorectal cancer and Biliary tract cancer.","summary":"Transcriptional activator that binds and transactivates ETS sequences containing the consensus nucleotide core sequence GGA[AT]. Acts synergistically with POU2F3 to transactivate the SPRR2A promoter and with RUNX1 to transactivate the ANGPT1 promoter. Also transactivates collagenase, CCL20, CLND7, FLG, KRT8, NOS2, PTGS2, SPRR2B, TGFBR2 and TGM3 promoters.\n\nOpen Targets scores its association with cancer at 0.61 (direct and indirect evidence; datatypes literature 0.98, animal model 0.27, genetic association 0.06, somatic mutation 0.78).
