Introduction:
Nuclear factor kB p65 (NF-kB p65) is encoded by the RELA gene and is present on chromosome 11 in humans. NF-kB P65 is also known as RelA (v-rel avian reticuloendotheliosis viral oncogene homolog A) and belongs to the Rel family of proteins. It is one of the two subunits of NF-kB (Nuclear factor kappa-light-chain-enhancer of activated B cells) that heterodimerizes with the other subunits p50 or p52. However, binding of TNF alpha to its cognate receptor phosphorylates IKK which in turn phosphorylates I kB allowing proteasomal degradation of I kB. It specifically plays a key role in transcription of immunoglobulin k (kappa) gene in mature B-lymphoid cells.
