TFDP1Transcription factor Dp-1 is a protein that in humans is encoded by the TFDP1 gene.FunctionThe E2F transcription factor family regulates the expression of various cellular promoters, particularly those involved in the cell cycle. E2F factors bind to DNA as homodimers or heterodimers in association with dimerization partner DP1. TFDP1 may be the first example of a family of related transcription factors; see TFDP2.InteractionsTFDP1 has been shown to interact with: E2F1, E2F5, and P53.
