Entrez Gene summary for NFKB2:

This gene encodes one of the subunits of the transcription factor complex nuclear factor-kappa-B (NFkB). The NFkB

transcription factor complex is expressed in numerous cell types and functions as a central activator of genes

involved in inflammation and immune function. The NFkB complex can consist of different subunits that form both homo-

or heterodimers which bind specific kappa-B elements in target genes. This gene encodes the p100 subunit that is

processed into the active p52 subunit. This protein can function as both a transcriptional activator and repressor,

depending on its dimer partner. Alternate splicing results in both coding and non-coding variants. (provided by

RefSeq, May 2012)

UniProtKB/Swiss-Prot: NFKB2_HUMAN, Q00653

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 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. 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. In a non-canonical activation pathway, the

MAP3K14-activated CHUK/IKKA homodimer phosphorylates NFKB2/p100 associated with RelB, inducing its proteolytic

processing to NFKB2/p52 and the formation of NF-kappa-B RelB-p52 complexes. The NF-kappa-B heterodimeric RelB-p52

complex is a transcriptional activator. The NF-kappa-B p52-p52 homodimer is a transcriptional repressor. NFKB2 appears

to have dual functions such as cytoplasmic retention of attached NF-kappa-B proteins by p100 and generation of p52 by

a cotranslational processing. The proteasome-mediated process ensures the production of both p52 and p100 and

preserves their independent function. p52 binds to the kappa-B consensus sequence 5'-GGRNNYYCC-3', located in the

enhancer region of genes involved in immune response and acute phase reactions. p52 and p100 are respectively the

minor and major form; the processing of p100 being relatively poor. Isoform p49 is a subunit of the NF-kappa-B protein

complex, which stimulates the HIV enhancer in synergy with p65

summary for NFKB2:

NF-kappaB (nuclear factor-kappa B) is a rapidly acting primary transcription factor found in all cell types.

It is involved in cellular responses to stimuli such as cytokines and stress and plays a key role in

regulating the immune response to infection. In unstimulated cells NF-kappaB dimers are sequestered

inactively in the cytoplasm by a protein complex called inhibitor of kappa B (IkappaB). IkappaB inactivates

NF-kappaB by masking the nuclear localization signals (NLS). Activation of NF-kappaB occurs via degradation

of IkappaB, a process that is initiated by its phosphorylation by IkappaB kinase (IKK). Phosphorylated IvB

becomes dissociated from NF-kappaB, unmasking the NLS. Phosphorylation also results in IkappaB

ubiquitination and targeting to the proteasome. NF-kappaB can now enter the nucleus and regulate gene

expression. NF-kappaB turns on expression of IkappaB forming a negative feedback loop.

Post-translational modifications:

While translation occurs, the particular unfolded structure after the GRR repeat promotes the generation of p52 making

it an acceptable substrate for the proteasome. This process is known as cotranslational processing. The processed form

is active and the unprocessed form acts as an inhibitor (I kappa B-like), being able to form cytosolic complexes with

NF-kappa B, trapping it in the cytoplasm. Complete folding of the region downstream of the GRR repeat precludes

processing¹

Subsequent to MAP3K14-dependent serine phosphorylation, p100 polyubiquitination occurs then triggering its

proteasome-dependent processing¹

Constitutive processing is tightly suppressed by its C-terminal processing inhibitory domain, named PID, which contains

the death domain¹
