The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Colorectal cancer, Breast cancer, Prostate cancer and 3 more.","summary":"Participates in the Wnt signalling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as a repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the presence of CTNNB1.\n\nOpen Targets scores its association with cancer at 0.83 (direct and indirect evidence; datatypes affected pathway 0.58, literature 0.97, genetic association 0.72, somatic mutation 0.96, animal model 0.49).
