Human c-Rel Antibody

c-Rel/Rel, the cellular counterpart of the v-Rel oncogene of the avian reticuloendotheliosis retrovirus, is a 85 kDa class II member of the Rel/NK-kappa B family of transcription factors. All Rel family members contain a RHD (Rel homology domain) that is involved in dimerization, DNA and I kappaB binding, and nuclear localization. Class II members contain an additional C-terminal transcriptional activation segment. Rel both homodimerizes and heterodimerizes with multiple family members. Following dimerization, Rel complexes initiate transcription by acting on decameric DNA motifs termed kappaB binding sites. c-Rel activity is regulated by phosphorylation and ubiquitination. The important role of c-Rel in B-cell development, growth, and survival is well documented. c-Rel is also involved in responses to auto-antigens, allo-antigens, allergens and pathogens and may contribute to the development of certain human lymphoid cell cancers.
