The NF-κB p100 (Phospho-Ser866) antibody is a specialized tool for studying the non-canonical NF-κB signaling pathway. NF-κB is a family of transcription factors regulating immune response, inflammation, and cell survival. The p100 protein, encoded by the NFKB2 gene, serves as both a precursor for the active subunit p52 and an inhibitory molecule in its unprocessed form. Phosphorylation at Ser866 is a critical post-translational modification that primes p100 for proteasomal processing into p52. This phosphorylation event is mediated by the kinase NIK (NF-κB-inducing kinase) and IKKα (Inhibitor of κB kinase α) in response to stimuli like CD40. BAFF, or lymphotoxin-β receptor activation.
The antibody specifically detects endogenous p100 phosphorylated at Ser866. enabling researchers to monitor pathway activation. It is widely used in techniques such as Western blotting, immunofluorescence, and immunoprecipitation to study cellular responses in immune cells, cancer models, or inflammatory conditions. Validation often includes testing in phosphorylation-deficient mutants or NIK/IKKα-inhibited systems to confirm specificity. Dysregulation of p100/p52 signaling is implicated in autoimmune diseases, lymphomas, and chronic inflammation, making this antibody valuable for both mechanistic research and therapeutic target validation. Proper controls, such as total p100/p52 detection and stimulus-dependent phosphorylation assays, are essential for accurate interpretation.
