NF-κB Antibody

Overview, pathway and related antibodies

Overview, pathway and related antibodies

Nuclear factor kappa B (NF-κB) is a protein complex that controls transcription of DNA, cytokine production and cell survival. NF-κB is composed of multiple subunits: RelA (p65), RelB, c-Rel, NF-κB1 (p50) and NF-κB2 (p52) (1).

These proteins function as dimeric transcription factors that regulate the expression of genes influencing a broad range of biological processes including innate and adaptive immunity, inflammation, stress responses, B-cell development, and lymphoid organogenesis (2). NF-κB exists freely in the cytoplasm, where it is inhibited by IκB proteins. In the classical (canonical) pathway, NF-κB activation occurs through the phosphorylation, ubiquitination and subsequent proteosomal degradation of IκB. An alternative (non-cononical) activation involves phosphorylation and processing of the p52 precursor, p100 into the mature protein and subsequent nuclear translocation of the RelB/p52, heterodimer that translocate to the nucleus and induce target gene expression (3).

Abnormalities in NF-κB pathway has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection, and improper immune development. NF-κB has also been implicated in processes of synaptic plasticity and memory (4,5).
