NFKB1 (Nuclear Factor Kappa B Subunit 1) is a Protein Coding gene. This gene encodes a 105 kD protein which can undergo cotranslational processing by the 26S proteasome to produce a 50 kD protein. The 105 kD protein is a Rel protein-specific transcription inhibitor and the 50 kD protein is a DNA binding subunit of the NF-kappa-B (NFKB) protein complex. NFKB is a transcription regulator that is activated by various intra- and extra-cellular stimuli such as cytokines, oxidant-free radicals, ultraviolet irradiation, and bacterial or viral products. Activated NFKB translocates into the nucleus and stimulates the expression of genes involved in a wide variety of biological functions. Diseases associated with NFKB1 include Immunodeficiency, Common Variable, 12, and Common Variable Immunodeficiency. Among its related pathways are GDNF-Family Ligands and Receptor Interactions and Apoptosis Modulation and Signaling.
