E2FA silencing leads to compromised cell proliferation and endocycle. Zoltán Magyar et al. EMBO J. 2012;31: ©2012 by European Molecular Biology Organization

RBR1 makes complex with E2FA in proliferating cells while it associates with E2FB in cells leaving cell proliferation. Zoltán Magyar et al. EMBO J. 2012;31: ©2012 by European Molecular Biology Organization

The pE2FA::gE2FA–GFP lines have increased expression of E2FA within its own expression domain that leads to more proliferation and endocycle compared with WT. (A) Two independent pE2FA::gE2FA–GFP lines (line 2/10 and line 81/11) were tested for the expressi... Zoltán Magyar et al. EMBO J. 2012;31: ©2012 by European Molecular Biology Organization
