NF-κB is a transcription factor activated by various extra and intracellular stimuli such as cytokines, UV radiation, stress, injury, and by bacterial and viral products. It is involved in regulation of various cellular events including cell growth, differentiation, proliferation, apoptosis, and inflammation. NF-κB1 (p50), a 50 kDa functional sub-unit of NF-κB, is a member of the Rel protein family. It is synthesized as a p105 precursor protein and consists of an N-terminal conserved RHD-region containing a nuclear localization signal, DNA-binding and dimerization domains. NF-κB (p50) forms homodimers or heterodimerizes with p65, forming the functional NF-κB factor. NF-κB (p50) directs the nuclear translocation of NF-κB and is instrumental in its DNA-binding. A pathological role of NF-κB has been suggested in AIDS, hematogenic cancer cell metastasis, and rheumatoid arthritis.WARNING This product is not for human or veterinary use.
