'''NMR structure of the DNA-binding TEA domain and insights into TEF-1 function'''<br />


==Overview==
==Overview==
Transcription enhancer factor 1 is essential for cardiac, skeletal, and, smooth muscle development and uses its N-terminal TEA domain (TEAD) to, bind M-CAT elements. Here, we present the first structure of TEAD and show, that it is a three-helix bundle with a homeodomain fold. Structural data, reveal how TEAD binds DNA. Using structure-function correlations, we find, that the L1 loop is essential for cooperative loading of TEAD molecules on, to tandemly duplicated M-CAT sites. Furthermore, using a microarray, chip-based assay, we establish that known binding sites of the full-length, protein are only a subset of DNA elements recognized by TEAD. Our results, provide a model for understanding the regulation of genome-wide gene, expression during development by TEA/ATTS family of transcription factors.
