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) [1].	Domain

Members of this family are found in various eukaryotic hypothetical proteins and in the DNA-binding protein LAG-1. They adopt a beta sandwich structure, with nine strands in two beta-sheets, in a Greek-key topology, and allow for DNA binding [1]. This domain is also known as RHR-N (Rel-homology region) as it related to Rel domain proteins.	Domain
