Entrez Summary: This gene encodes a member of the DP family of transcription factors. These factors heterodimerize with E2F proteins to enhance their DNA-binding activity and promote transcription from E2F target genes. This protein functions as a negative regulator and inhibits the DNA binding and transcriptional activities of E2F factors.[provided by RefSeq, May 2010].
UniProt Summary: Competitive inhibitor of E2F-mediated transactivation activity. Impairs E2F-mediated cell-cycle progression from G(1) to S phase. {ECO:0000269|PubMed:16418725, ECO:0000269|PubMed:17062573, ECO:0000269|PubMed:20559320}.
