CDCA7L is a member of the CDCA (cell division cycle associated) protein family. Members of this family have expression patterns associated with other known cell cycle genes such as cyclins and CDC genes. CDCA7L plays a role in transcriptional regulation as a repressor that inhibits monoamine oxidase A (MAOA) activity and gene expression by binding to the promoter. It also plays an important oncogenic role in mediating the full transforming effect of MYC in medulloblastoma cells. It is involved in apoptotic signaling pathways and may act downstream of P38-kinase and BCL-2, but upstream of CASP3/caspase-3 as well as CCND1/cyclin D1 and E2F1.
