 205-310 5.70e-46

Dimerization domain of E2F transcription factors; E2F transcription factors are involved in the regulation of DNA synthesis, cell cycle progression, proliferation and apoptosis. It associates with the retinoblastoma (Rb) protein, negatively regulating the G1-S transition until cyclin-dependent kinases phosphorylate Rb, which causes E2F release. E2F forms heterodimers with DP, a distantly related protein. Heterodimerization enhances the Rb binding, DNA binding, and transactivation activities of E2Fs. In humans, there are at least six closely related E2F and two DP family members, all containing a DNA-binding domain, a coiled-coil (CC) region, and a marked-box domain. E2F1 to E2F5 also contain a C-terminal transactivation domain.

 130-194 2.78e-33

E2F/DP family winged-helix DNA-binding domain; This family contains the transcription factor E2F and its dimerization partners TDP1 and TDP2, which stimulate E2F-dependent transcription. E2F binds to DNA as a homodimer or as a heterodimer in association with TDP1/2, the heterodimer having increased binding efficiency. The crystal structure of an E2F4-DP2-DNA complex shows that the DNA-binding domains of the E2F and DP proteins both have a fold related to the winged-helix DNA-binding motif. Recognition of the central c/gGCGCg/c sequence of the consensus DNA-binding site is symmetric, and amino acids that contact these bases are conserved among all known E2F and DP proteins.
