E2F5 Products

The protein encoded by the E2F5 gene is a member of the E2F family of transcription factors. The E2F family plays a crucialrole in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transformingproteins of small DNA tumor viruses. The E2F proteins contain several evolutionarily conserved domains that arepresent in most members of the family. These domains include a DNA binding domain, a dimerization domain whichdetermines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domainenriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within thetransactivation domain. This protein is differentially phosphorylated and is expressed in a wide variety of humantissues. It has higher identity to E2F4 than to other family members. Both this protein and E2F4 interact with tumorsuppressor proteins p130 and p107, but not with pRB. Alternative splicing results in multiple variants encodingdifferent isoforms. (provided by RefSeq)
