Definition:

Acts as transcriptional regulator and plays a role in gene silencing. Probably forms a corepressor complex required for activated KRAS-mediated promoter hypermethylation and transcriptional silencing of several tumor suppressor genes (TSGs) or other tumor-related genes in colorectal cancer (CRC) cells. Also required to maintain a transcriptionally repressive state of genes in undifferentiated embryonic stem cells (ESCs) by inducing trimethylation of 'Lys-27' of histone H3 (H3K27me3) in a Polycomb group (PcG) complexes-dependent manner. Associates at promoter regions of TSGs and mediates the recruitment of the corepressor complex containing the scaffolding protein TRIM28, methyltransferase DNMT1 and histone methyltransferase SETDB1 and/or the PcG complexes at those sites. Transcription factor involved in the metastatic cascade process by inducing cell migration and proliferation and gain resistance to anoikis of ovarian carcinoma (OC) cells via integrin-mediated signaling pathways. Associates with the ITGB1 promoter and positively regulates beta-1 integrin transcription expression. Promotes angiogenesis. Promotes tumor growth.
