STRUCTURE OF TRANSCRIPTION FACTOR GENESIS/DNA COMPLEX
Structural highlights
FunctionFOXD3_RAT Binds to the consensus sequence 5'-A[AT]T[AG]TTTGTTT-3' and acts as a transcriptional repressor. Also acts as a transcriptional activator. Promotes development of neural crest cells from neural tube progenitors. Restricts neural progenitor cells to the neural crest lineage while suppressing interneuron differentiation. Required for maintenance of pluripotent cells in the pre-implantation and peri-implantation stages of embryogenesis (By similarity). Evolutionary ConservationCheck, as determined by ConSurfDB.

By using multi-dimensional NMR techniques, we have obtained the solution structure and backbone dynamics of Genesis complexed with a 17 base-pair DNA. Our results indicate that both the local folding and dynamic properties of Genesis are perturbed when it binds to the DNA site. Our data show that a conserved flexible amino acid sequence (wing 1) makes dynamic contacts to DNA in the complex and a short helix is induced by Genesis-DNA interactions. Our data indicate that, unlike the HNF-3gamma/DNA complex, a magnesium ion is not required in forming the stable Genesis-DNA complex. Dynamic DNA contacts observed in the NMR structure of winged helix protein-DNA complex.,Jin C, Marsden I, Chen X, Liao X J Mol Biol. 1999 Jun 18;289(4):683-90.
