Background
The NF-κB p105 precursor protein is a 105 kDa cytoplasmic ankyrin-repeat-rich molecule that undergoes stimulus-dependent, ubiquitin/proteasome-mediated processing to liberate the 50 kDa DNA-binding p50 subunit, which then dimerizes with other NF-κB/Rel members to form transcriptionally active complexes that rapidly enter the nucleus and regulate genes governing immunity, inflammation, cell survival, and proliferation; p105 itself also serves as an IκB-like inhibitor by sequestering associated dimers in the cytoplasm, and its balanced processing versus full-length stability is tightly controlled by IKK-mediated phosphorylation, ensuring dynamic NF-κB signaling in response to cytokines, pathogens, and cellular stresses.
