E2F1 is a member of E2F group of proteins that share common structural and functional domains and plays a major role during the G1/S transition in the mammalian cell cycle as a transcriptional factor. E2F1 is regulated during cell cycle progression. It is phosphorylated at Ser364 by Chk2 kinase in response to DNA damage, stabilized, mobilized to nucleus and activated as a transcription factor . It induces apoptosis by activating transcription of the p53 homolog, p73 (3). E2F1 protein consists of 437 amino acids with a molecular mass of 46 kDa.

1) Western blotting (-1 ug/ml)
Not tested for other applications.
Identification of E2F1 protein phosphorylated at p-Ser364 with monoclonal antibody (#2).
MCF cells were grown in the absence (lane 1) or in the presence of etoposide at 10 μM for 16 h (lanes 2 & 3). Crude lysates were prepared and analyzed by Western blotting (lane 3) with the antibody #2 or immunoprecipitated by pantropic anti-E2F1 antibody followed by Western blotting with the antibody #2
