      Background InformationThe transcription factor NFκB (Nuclear Factor κB) is involved in the expression and regulation of a number of important cellular and physiological processes such as growth, development, apoptosis, immune and inflammatory response, and activation of various viral promoters including human immunodeficiency virus long terminal repeats. NFκB represents a group of structurally related and evolutionarily conserved proteins related to the proto-oncogene c-Rel with five members in mammals that include Rel (cRel), RelA (p65), RelB, NFκB1 (p50 and its precursor p105), and NFκB2 (p52 and its precursor p100). NFκB/Rel proteins exist as homo- or heterodimers to form transcriptionally competent or repressive complexes. Although most NFκB dimers are activators of transcription, the p50/50 and p52/52 homodimers can repress the transcription of their target genes. The p50/p65 heterodimer of NFκB is the most abundant in cells.

      Entrez Gene Number
      Entrez Gene SummaryNFKB1 (MIM 164011) or NFKB2 (MIM 164012) is bound to REL (MIM 164910), RELA, or RELB (MIM 604758) to form the NFKB complex. The p50 (NFKB1)/p65 (RELA) heterodimer is the most abundant form of NFKB. The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA, MIM 164008 or NFKBIB, MIM 604495), which inactivate NFKB by trapping it in the cytoplasm. Phosphorylation of serine residues on the I-kappa-B proteins by kinases (IKBKA, MIM 600664, or IKBKB, MIM 603258) marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NFKB complex. Activated NFKB complex translocates into the nucleus and binds DNA at kappa-B-binding motifs such as 5-prime GGGRNNYYCC 3-prime or 5-prime HGGARNYYCC 3-prime (where H is A, C, or T; R is an A or G purine; and Y is a C or T pyrimidine).[supplied by OMIM]

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q04206 # p65 is a subunit of the nuclear factor kappa-B, a second messenger, which activates the transcription of a number of genes in multiple tissues. The inhibitory effect of I-kappa-B upon NF- kappa-B in the cytoplasm is exerted primarily through the interaction with p65. p65 shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kappa-B complex.
      SIZE: 551 amino acids; 60219 Da
      SUBUNIT: Active NF-kappa-B is a heterodimer of an about 50 kDa DNA-binding subunit and the weak DNA-binding subunit p65. Two heterodimers might form a labile tetramer. May interact with ETHE1. Binds AES and TLE1. Interacts with TP53BP2. Binds to and is phosphorylated by the activated form of either RPS6KA4 or RPS6KA5. Interacts with ING4 and this interaction may be indirect. Interacts with CARM1, USP48 and UNC5CL.
      SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Nuclear, but also found in the cytoplasm in an inactive form complexed to an inhibitor (I-kappa-B).
      PTM: Ubiquitinated, leading to its proteosomal degradation. Degradation is required for termination of NF-kappa-B response.
      SIMILARITY: SwissProt: Q04206 ## Contains 1 RHD (Rel-like) domain.
