Rel homology domain (IPR011539)

Short name: RHD

Domain relationships


The Rel homology domain (RHD) is found in a family of eukaryotic transcription factors, which includes NF-kappaB, Dorsal, Relish, NFAT, among others. Some of these transcription factors appear to form multi-protein DNA-bound complexes [PMID: 9794820]. Phosphorylation of the RHD appears to play a role in the regulation of some of these transcription factors, acting to modulate the expression of their target genes [PMID: 15516339]. The RHD is composed of two immunoglobulin-like beta-barrel subdomains that grip the DNA in the major groove. The N-terminal specificity domain resembles the core domain of the p53 transcription factor, and contains a recognition loop that interacts with DNA bases; the C-terminal dimerisation domain contains the site for interaction with I-kappaB [PMID: 7830764].
