Plays a role in transcriptional regulation as a repressor that inhibits monoamine oxidase A (MAOA) activity and gene expression by binding to the promoter. Plays an important oncogenic role in mediating the full transforming effect of MYC in medulloblastoma cells. Involved in apoptotic signaling pathways; May act downstream of P38- kinase and BCL-2, but upstream of CASP3/caspase-3 as well as CCND1/cyclin D1 and E2F1. {ECO:0000269|PubMed:15654081, ECO:0000269|PubMed:15994933, ECO:0000269|PubMed:16829576}. This is the function of ENSG00000164649 (CDCA7L, cell division cycle associated 7 like).
