Biolegend, 603902, Purified anti-NF-κB p105/p50 Antibody

NF-κB p105/p50 is the class 1 member of the nuclear factor of kappa light polypeptide gene enhancer in B-cells (NF-κB) transcription factor family. NFKB1 is synthesized as a longer precursor protein, p105, which can be prolytically processed into shorter proteins, p50 and IκBγ. Both p105 and IκBγ proteins contain IκB-like ankyrin repeats that can act as NF-κB inhibitors. P50 protein forms active DNA-binding heterodimers with RelA/NF-κB p65 and c-REL. Stimulation by inflammatory signals, such as TNFα, IL-1, and LPS, lead to the proteosomal degradation of IκBα and result in the translocation of RelA/NF-κB p65:p50 and c-Rel:p50 heterodimers to the nucleus. Subsequently, the nuclear NF-κB subunits bind to target genes and regulate gene transcription. NFKB1 is a key component of the NF-κB signaling pathway and is involved in the regulation of various biological processes including cell proliferation, differentiation, apoptosis, and immune responses.
