Transcription factor E2F1 is a
protein that in humans is encoded by the E2F1gene.[5]
Function
The protein encoded by this gene is a member of the E2F family of
transcription factors. The E2F family plays a crucial role in the control of
cell cycle and action of
tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. The E2F proteins contain several evolutionarily conserved domains found in most members of the family. These domains include a
DNA binding domain, a dimerization domain which determines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F2 and E2F3, have an additional cyclin binding domain. This protein binds preferentially to
retinoblastoma protein pRB in a cell-cycle dependent manner. It can mediate both cell proliferation and
p53-dependent/independent
apoptosis.[6]
