'''Crystal structure of activated Notch, CSL and MAML on HES-1 promoter DNA sequence'''<br />
'''Crystal structure of activated Notch, CSL and MAML on HES-1 promoter DNA sequence'''<br />


==Overview==
==Overview==
Notch receptors transduce essential developmental signals between, neighboring cells by forming a complex that leads to transcription of, target genes upon activation. We report here the crystal structure of a, Notch transcriptional activation complex containing the ankyrin domain of, human Notch1 (ANK), the transcription factor CSL on cognate DNA, and a, polypeptide from the coactivator Mastermind-like-1 (MAML-1). Together, CSL, and ANK create a groove to bind the MAML-1 polypeptide as a kinked, 70 A, helix. The composite binding surface likely restricts the recruitment of, MAML proteins to promoters on which Notch:CSL complexes have been, preassembled, ensuring tight transcriptional control of Notch target, genes.
