Descripción

General description

Nuclear factor NF-kappa-B p105 subunit (UniProt P19838; also known as DNA-binding factor KBF1, EBP-1, NF-kappa-B, NF-kappaB, NF-kB1, NFkappaB, NFKB-p105, NFKB-p50, Nuclear factor NF-kappa-B p50 subunit, Nuclear factor kappa-B DNA binding subunit, Nuclear factor of kappa light polypeptide gene enhancer in B-cells 1) is encoded by the NFKB1 gene (Gene ID 4790) in human. NF-κB is a protein complex that plays a key role in regulating the immune response to infection/inflammation. NF-κB1 is synthesized as a 968 a.a protein (p105), which undergoes posttranslational processing to generate the p50 subunit (a.a. 1-433). The p50 NF-κB participates in target gene transactivation by forming heterodimers with RelA, RelB, or c-Rel. In addition, p50 homodimer can bind the nuclear protein Bcl-3 and form a functional transcriptional activator complex. In unstimulated cells, the NF-κB dimers are sequestered in the cytoplasm by the family of IκB (Inhibitor of κB) proteins (IκBα, IκBβ, IκBε, and Bcl-3). Upon stimulation, IκB becomes phosphorylated by the IκB kinase (IKK) complex, leading to IκB ubiquitination and proteasomal degradation. With the degradation of IκB, the NF-κB complex is then freed to enter the nucleus to activate the transcription of target genes.

Specificity

Dectects 105 kDa recursor and 50 kDa processed forms. Immunogen sequence is a.a. 1-12, this polyclonal antibody can therefore detect isoforms 1 and 2, but not 3. Note that isoform 3 is missing amino acids 1-180.

Immunogen

Epitope: Amino acid 1-12

KLH conjugated synthetic peptide (MAEDDPYLGRPE-C) corresponding to amino acids 1-12 of NFκB p50, containing a C-terminal cysteine.
