PFAM accession number:PF00554
Interpro abstract (IPR011539):

The Rel homology domain (RHD) is found in a family of eukaryotic transcription factors, which includes NF-kappaB, Dorsal, Relish, NFAT, among others. The RHD is composed of two structural domains: the N-terminal DNA binding domain that is similar to that found in P53, the C-terminal domain has an immunoglobulin-like fold (See ) that functions as a dimerisation domain. This entry represents the N-terminal DNA binding domain [ (PUBMED:17869269) ].

Some of these transcription factors appear to form multi-protein DNA-bound complexes [ (PUBMED: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 [ (PUBMED: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 [ (PUBMED:7830764) ].

GO process:regulation of transcription, DNA-templated (GO:0006355)
GO function:DNA binding (GO:0003677), DNA-binding transcription factor activity (GO:0003700)
