CC -!- FUNCTION: NF-kappa-B is a pleiotropic transcription factor present in
CC almost all cell types and is the endpoint of a series of signal
CC transduction events that are initiated by a vast array of stimuli
CC related to many biological processes such as inflammation, immunity,
CC differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B
CC is a homo- or heterodimeric complex formed by the Rel-like domain-
CC containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and
CC NFKB2/p52 and the heterodimeric p65-p50 complex appears to be most
CC abundant one. The dimers bind at kappa-B sites in the DNA of their
CC target genes and the individual dimers have distinct preferences for
CC different kappa-B sites that they can bind with distinguishable
CC affinity and specificity. Different dimer combinations act as
CC transcriptional activators or repressors, respectively. NF-kappa-B is
CC controlled by various mechanisms of post-translational modification and
CC subcellular compartmentalization as well as by interactions with other
CC cofactors or corepressors. NF-kappa-B complexes are held in the
CC cytoplasm in an inactive state complexed with members of the NF-kappa-B
CC inhibitor (I-kappa-B) family. In a conventional activation pathway, I-
CC kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to
CC different activators, subsequently degraded thus liberating the active
CC NF-kappa-B complex which translocates to the nucleus. NF-kappa-B
CC heterodimeric p65-p50 and RelB-p50 complexes are transcriptional
CC activators. The NF-kappa-B p50-p50 homodimer is a transcriptional
CC repressor, but can act as a transcriptional activator when associated
CC with BCL3. NFKB1 appears to have dual functions such as cytoplasmic
CC retention of attached NF-kappa-B proteins by p105 and generation of p50
CC by a cotranslational processing. The proteasome-mediated process
CC ensures the production of both p50 and p105 and preserves their
CC independent function, although processing of NFKB1/p105 also appears to
CC occur post-translationally. p50 binds to the kappa-B consensus sequence
CC 5'-GGRNNYYCC-3', located in the enhancer region of genes involved in
CC immune response and acute phase reactions. In a complex with MAP3K8,
CC NFKB1/p105 represses MAP3K8-induced MAPK signaling; active MAP3K8 is
CC released by proteasome-dependent degradation of NFKB1/p105 (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the NF-kappa-B p65-p50 complex (By similarity).
CC Homodimer; component of the NF-kappa-B p50-p50 complex (By similarity).
CC Component of the NF-kappa-B p105-p50 complex (By similarity). Component
CC of the NF-kappa-B p50-c-Rel complex (By similarity). Component of a
CC complex consisting of the NF-kappa-B p50-p50 homodimer and BCL3 (By
CC similarity). Also interacts with MAP3K8 (By similarity). NF-kappa-B p50
CC subunit interacts with NCOA3 coactivator, which may coactivate NF-
CC kappa-B dependent expression via its histone acetyltransferase activity
CC (By similarity). Interacts with DSIPI; this interaction prevents
CC nuclear translocation and DNA-binding (By similarity). Interacts with
CC SPAG9 and UNC5CL (By similarity). NFKB1/p105 interacts with CFLAR; the
CC interaction inhibits p105 processing into p50 (By similarity).
CC NFKB1/p105 forms a ternary complex with MAP3K8 and TNIP2 (By
CC similarity). Interacts with GSK3B; the interaction prevents processing
CC of p105 to p50 (By similarity). NFKB1/p50 interacts with NFKBIE (By
CC similarity). NFKB1/p50 interacts with NFKBIZ. Nuclear factor NF-kappa-B
CC p50 subunit interacts with NFKBID (By similarity). Directly interacts
CC with MEN1 (By similarity). Interacts with HIF1AN (By similarity).
CC Interacts with FEM1A; interaction is direct (By similarity).

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Note=Nuclear, but also found in the cytoplasm in an inactive form
CC complexed to an inhibitor (I-kappa-B). {ECO:0000250}.
CC -!- DOMAIN: The C-terminus of p105 might be involved in cytoplasmic
CC retention, inhibition of DNA-binding by p50 homodimers, and/or
CC transcription activation.
CC -!- PTM: While translation occurs, the particular unfolded structure after
CC the GRR repeat promotes the generation of p50 making it an acceptable
CC substrate for the proteasome. This process is known as cotranslational
CC processing. The processed form is active and the unprocessed form acts
CC as an inhibitor (I kappa B-like), being able to form cytosolic
CC complexes with NF-kappa B, trapping it in the cytoplasm. Complete
CC folding of the region downstream of the GRR repeat precludes processing
CC (By similarity). {ECO:0000250}.
CC -!- PTM: Phosphorylation at 'Ser-931' and 'Ser-936' are required for
CC BTRC/BTRCP-mediated proteolysis. {ECO:0000250}.
CC -!- PTM: S-nitrosylation of Cys-61 affects DNA binding. {ECO:0000250}.
CC -!- PTM: The covalent modification of cysteine by 15-deoxy-Delta12,14-
CC prostaglandin-J2 is autocatalytic and reversible. It may occur as an
CC alternative to other cysteine modifications, such as S-nitrosylation
CC and S-palmitoylation (By similarity). {ECO:0000250}.
