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. Inappropriate activation of NFKB has been associated with a number of inflammatory diseases while persistent inhibition of NFKB leads to inappropriate immune cell development or delayed cell growth. NFKB is a critical regulator of the immediate-early response to viral infection. Alternative splicing results in multiple transcript variants encoding different isoforms, at least one of which is proteolytically processed. [provided by RefSeq, Aug 2020]
A study in pigs demonstrated that the mRNA expression of the NFKB1 was upregulated in bruises at 2 hours post-injury and then decreased at 5 and 8 hours relative to control tissue [Barington et al. DOI:10.1016/J.Jflm.2018.06.005]. In a rat model of traumatic brain injury, the NFKB1 gene was upregulated in the cerebral cortex at 3, 6, and 12 hours post-injury, with its expression pattern associated with the inflammatory response preceding apoptosis [Shojo et al. DOI:10.1016/j.neuroscience.2010.10.018].
