BD Pharmingen™ Purified Mouse anti-TBK1 (pS172)

NF-κB is a ubiquitously expressed transcription factor that regulates many cytokine and Ig genes.  It is involved in immune, inflammatory, viral, and acute phase responses.  In most cells, NF-κB is sequestered in an inactive cytoplasmic form via interactions with the inhibitory proteins IκBα, IκBβ, and IκBε.  Stimulation induces the release, activation, and nuclear translocation of NF-κB.  Release of NF-κB results from the phosphorylation and proteolytic degradation of the IκB proteins.  Two cytokine-inducible IκB kinases (IKKα and IKKβ) phosphorylate and target the IκB proteins for degradation via the ubiquitin pathway.  IKKγ/NEMO, a third member of the IKK complex, functions as a regulatory subunit and interacts directly with IKKβ.  TBK1 (TANK-binding kinase 1, also known as T2K or NAK), a protein of 729 amino acids, is another member of the IKK family of kinases regulating NF-κB downstream of the tumor necrosis factor and Toll-like receptor pathways.  TBK1 forms a complex with the adaptor proteins TANK (TRAF-associated NF-κB activator) and TRAF2 (TNF-receptor-associated factor 2), and this oligomer is required for activation and phosphorylation of TBK1 at serine 172 (S172).

The J133-1171 monoclonal antibody recognizes the phosphorylated S172 of human TBK1.
