== Publication Abstract from PubMed ==
Progression through the middle phase of sporulation in Saccharomyces cerevisiae is promoted by the successful completion of recombination at the end of prophase I. Completion of meiotic recombination allows the activation of the sporulation-specific transcription factor Ndt80, which binds to a specific DNA sequence, the middle sporulation element (MSE), and activates approximately 150 genes to enable progression through meiosis. Here, we isolate the DNA-binding domain of Ndt80 and determine its crystal structure both free and in complex with an MSE-containing DNA. The structure reveals that Ndt80 is a member of the Ig-fold family of transcription factors. The structure of the DNA-bound form, refined at 1.4 A, reveals an unexpected mode of recognition of 5'-pyrimidine- guanine-3' dinucleotide steps by arginine residues that simultaneously recognize the 3'-guanine base through hydrogen bond interactions and the 5'-pyrimidine through stacking/van der Waals interactions. Analysis of the DNA-binding affinities of MSE mutants demonstrates the central importance of these interactions, and of the AT-rich portion of the MSE. Functional similarities between Ndt80 and the Caenorhabditis elegans p53 homolog suggest an evolutionary link between Ndt80 and the p53 family.

Structural highlights

1mnn is a 3 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.4Å

Function

NDT80_YEAST Transcription factor required for successful completion of meiosis and spore formation. Gets activated after completion of meiotic recombination at the end of prophase I. Recognizes and binds to the middle sporulation element (MSE) 5'-C[AG]CAAA[AT]-3' in the promoter region of stage-specific genes that are required for progression through meiosis and sporulation. Competes for binding to MSE with the transcriptional repressor SUM1, which represses middle sporulation-specific genes during mitosis and early sporulation.[1] [2] [3] [4]
