Nuclear factor NF-kappa-B p105 subunit is a protein that in humans is encoded by the NFKB1 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-kappaB (NF-κB) protein complex.
