Yamasaki et al., Biochim Biophys Acta 1999 (Neoplasms) : At sites where E2F-1 contributes mainly to proliferation and p53 levels remain low, loss of E2F-1 expression may lead to tissue atrophy and overexpression may lead to hyperplasia or tumors

Hershko et al., Cell Death Differ 2005 : However, it is not known how E2F directs p53 activity towards apoptosis rather than growth arrest ... We demonstrate that activation of E2F1 leads to phosphorylation of p53 on serine 46 and this modification is important for E2F1-p53 cooperation in apoptosis
Fogal et al., EMBO J 2005 : E2F1 binds residues 347-370 of p53 and enhances nuclear retention of Ser315 phosphorylated p53 ... This regulation of p53 by E2F1 is cell cycle dependent, as the cellular distribution of Ser315 phosphorylated p53 is associated with the periodic expression of E2F and cyclin A throughout the cell cycle ... This is the first demonstration that the activities of p53 are regulated during the cell cycle by E2F/p53 interactions and that phosphorylation of p53 at Ser315 is required for this regulation
