== Publication Abstract from PubMed == | |||
Early B-cell factor 1 (Ebf1) is a key transcriptional determinant of B-lymphocyte differentiation whose DNA-binding domain has no sequence similarity to other transcription factor families. Here we report the crystal structure of an Ebf1 dimer bound to its palindromic recognition site. The DNA-binding domain adopts a pseudoimmunoglobulin-like fold with novel topology, but is structurally similar to the Rel homology domains of NFAT and NF-kappaB. Ebf1 contacts the DNA with two loop-based modules and a unique Zn coordination motif whereby each Ebf1 monomer interacts with both palindromic half-sites. This unusual mode of DNA recognition generates an extended contact area that may be crucial for the function of Ebf1 in chromatin. | |||
