| Function FUNCTION: NF-kappa-B is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The heterodimeric RELA-NFKB1 complex appears to be most abundant one. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. The NF-kappa-B heterodimeric RELA-NFKB1 and RELA-REL complexes, for instance, function as transcriptional activators. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. The inhibitory effect of I-kappa-B on NF-kappa-B through retention in the cytoplasm is exerted primarily through the interaction with RELA. RELA shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kappa-B complex. Beside its activity as a direct transcriptional activator, it is also able to modulate promoters accessibility to transcription factors and thereby indirectly regulate gene expression. Associates with chromatin at the NF-kappa-B promoter region via association with DDX1. Essential for cytokine gene expression in T-cells (PubMed:15790681). The NF-kappa-B homodimeric RELA-RELA complex appears to be involved in invasin-mediated activation of IL-8 expression. Key transcription factor regulating the IFN response during SARS-CoV-2 infection (PubMed:33440148). {ECO:0000269|PubMed:10928981, ECO:0000269|PubMed:12748188, ECO:0000269|PubMed:15790681, ECO:0000269|PubMed:17000776, ECO:0000269|PubMed:17620405, ECO:0000269|PubMed:19058135, ECO:0000269|PubMed:19103749, ECO:0000269|PubMed:20547752, ECO:0000269|PubMed:33440148}. |

| Post-translational modification PTM: Ubiquitinated by RNF182, leading to its proteasomal degradation (PubMed:31432514). Degradation is required for termination of NF-kappa-B response. Polyubiquitinated via 'Lys-29'-linked ubiquitin; leading to lysosomal degradation (PubMed:21518757). {ECO:0000269|PubMed:15226358, ECO:0000269|PubMed:21518757, ECO:0000269|PubMed:31432514}.; PTM: Monomethylated at Lys-310 by SETD6 (PubMed:21515635). Monomethylation at Lys-310 is recognized by the ANK repeats of EHMT1 and promotes the formation of repressed chromatin at target genes, leading to down-regulation of NF-kappa-B transcription factor activity. Phosphorylation at Ser-311 disrupts the interaction with EHMT1 without preventing monomethylation at Lys-310 and relieves the repression of target genes (By similarity). {ECO:0000250|UniProtKB:Q04207, ECO:0000269|PubMed:21515635}.; PTM: Phosphorylation at Ser-311 disrupts the interaction with EHMT1 and promotes transcription factor activity (By similarity). Phosphorylation on Ser-536 stimulates acetylation on Lys-310 and interaction with CBP; the phosphorylated and acetylated forms show enhanced transcriptional activity. Phosphorylation at Ser-276 by RPS6KA4 and RPS6KA5 promotes its transactivation and transcriptional activities. {ECO:0000250, ECO:0000269|PubMed:10521409, ECO:0000269|PubMed:10938077, ECO:0000269|PubMed:11931769, ECO:0000269|PubMed:12456660, ECO:0000269|PubMed:12628924, ECO:0000269|PubMed:14690596, ECO:0000269|PubMed:15073167, ECO:0000269|PubMed:15516339, ECO:0000269|PubMed:15775976, ECO:0000269|PubMed:16046471, ECO:0000269|PubMed:16135789, ECO:0000269|PubMed:16407239, ECO:0000269|PubMed:17000776, ECO:0000269|PubMed:19103749}.; PTM: Phosphorylation at Ser-75 by herpes simplex virus 1/HHV-1 inhibits NF-kappa-B activation. {ECO:0000269|PubMed:24807716}.; PTM: Reversibly acetylated; the acetylation seems to be mediated by CBP, the deacetylation by HDAC3 and SIRT2. Acetylation at Lys-122 enhances DNA binding and impairs association with NFKBIA. Acetylation at Lys-310 is required for full transcriptional activity in the absence of effects on DNA binding and NFKBIA association. Acetylation at Lys-310 promotes interaction with BRD4. Acetylation can also lower DNA-binding and results in nuclear export. Interaction with BRMS1 promotes deacetylation of Lys-310. Lys-310 is deacetylated by SIRT2. {ECO:0000269|PubMed:12419806, ECO:0000269|PubMed:12456660, ECO:0000269|PubMed:16135789, ECO:0000269|PubMed:17000776, ECO:0000269|PubMed:19103749}.; PTM: S-nitrosylation of Cys-38 inactivates the enzyme activity. {ECO:0000250}.; PTM: Sulfhydration at Cys-38 mediates the anti-apoptotic activity by promoting the interaction with RPS3 and activating the transcription factor activity. {ECO:0000250}.; PTM: Sumoylation by PIAS3 negatively regulates DNA-bound activated NF-kappa-B. {ECO:0000269|PubMed:22649547}.; PTM: Proteolytically cleaved within a conserved N-terminus region required for base-specific contact with DNA in a CPEN1-mediated manner, and hence inhibits NF-kappa-B transcriptional activity (PubMed:18212740). {ECO:0000269|PubMed:18212740}. |
| Domain DOMAIN: The transcriptional activation domain 3/TA3 does not participate in the direct transcriptional activity of RELA but is involved in the control by RELA of the accessibility of target gene promoters. Mediates interaction with ZBTB7A. {ECO:0000250|UniProtKB:Q04207}.; DOMAIN: The transcriptional activation domain 1/TA1 and the transcriptional activation domain 2/TA2 have direct transcriptional activation properties (By similarity). The 9aaTAD motif found within the transcriptional activation domain 2 is a conserved motif present in a large number of transcription factors that is required for their transcriptional transactivation activity (PubMed:17467953). {ECO:0000250|UniProtKB:Q04207, ECO:0000269|PubMed:17467953}. |
| Involvement in disease DISEASE: Note=A chromosomal aberration involving ZFTA is found in more than two-thirds of supratentorial ependymomas. Translocation with ZFTA produces a ZFTA-RELA fusion protein. ZFTA-RELA translocations are potent oncogenes that probably transform neural stem cells by driving an aberrant NF-kappa-B transcription program (PubMed:24553141). {ECO:0000269|PubMed:24553141}.; DISEASE: Autoinflammatory disease, familial, Behcet-like 3 (AIFBL3) [MIM:618287]: An autosomal dominant, mucocutaneous disease characterized by chronic mucosal lesions, in absence of recurrent infections. {ECO:0000269|PubMed:28600438}. Note=The disease may be caused by variants affecting the gene represented in this entry. |
