E2F function in muscle growth is necessary and sufficient for viability in Drosophila

Abstract

The transcriptional regulators E2F/Dp play a critical role in cell-cycle regulation, but it is unclear why E2F-deficient flies die. Here, the authors show this is linked to the function of E2F in adult Drosophilaskeletal muscle, with the contribution of E2f1 being most important in post-fusion muscle.
