E2F transcription factors are key components of the RB/E2F pathway that, through action cyclin-dependent kinases, regulates cell cycle progression in both plants and animals. Moreover, plant animal E2Fs have also been shown to regulate other cellular functions addition proliferation. Based on structural functional features, they can be divided into different classes that act as activators or re...
