'''STRUCTURE OF TRANSCRIPTION FACTOR GENESIS/DNA COMPLEX'''<br />


==Overview==
==STRUCTURE OF TRANSCRIPTION FACTOR GENESIS/DNA COMPLEX==
Genesis is an HNF-3/fkh homologous protein. 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.

Function

FOXD3_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).
