Beta-trefoil DNA-binding domain
SMART accession number:SM01268
Description: Members of this family of DNA binding domains adopt a beta-trefoil fold, that is, a capped beta-barrel with internal pseudo threefold symmetry. In the DNA-binding protein LAG-1, it also is the site of mutually exclusive interactions with NotchIC (and the viral protein EBNA2) and co-repressors (SMRT/N-Cor and CIR) (PUBMED:15297877).
