NCIt definition : Nuclear factor NF-kappa-B p100 subunit (900 aa, 97 kDa) is encoded by the human NFKB2
gene. This protein plays a role in both transcriptional regulation and signal transduction.;
NCIt note : 100Kd and 49Kd products by alternate splicing; Nuclear factor NF-kappa-B p100 subunit is proteolytically processed to form nuclear
factor NF-kappa-B p52 subunit.; NFKB2 belongs to the Rel/Dorsal family, contains seven ANK repeats, and binds to REL
(p65) proteins to form NFKB, which is trapped in the cytoplasm by IkB proteins. IkB
phosphorylation by IKBKA or IKBKB activates NFKB via destructive ubiquitination of
IkBs. Activated transcription factor NFKB translocates to the nucleus and binds to
the consensus Kappa-B enhancer DNA motif in immune response and acute phase reaction
genes. (from SWISS-PROT Q00653, OMIM 164012, and NCI);
