E2F4, along with E2F5, belong to the second group of the E2F family of transcription factors. E2F4 accounts for the majority of the E2F proteins in many cell types. They associate preferentially with pocket proteins p107 and p130. E2F4 is required for cell cycle arrest in G1 induced by the cyclin-dependent kinase inhibitor p16INK4a. Gaubatz et al. showed that E2F4, as well as E2F5, shuttles between the nucleus and the cytoplasm. LMB inhibits nuclear export of E2F4 and E2F5. By deletion and mutation studies, they showed that there are two NES motifs in E2F4, one between aa 61-70, the other between 91-100. Mutation at either I68/L70 or at L97/I98 makes the protein nuclear even in the absence of LMB. Over-expression of CRM1 can relocate the single NES mutant from the nucleus to the cytoplasm.

Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus.
Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb
by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
