Protocols

Specificity / Sensitivity

TBK1 Antibody detects endogenous levels of total TBK1/NAK protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy-terminus of TBK1/NAK. Antibodies were purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa (human), BaF3 (mouse) and KNRK (rat) cell lines, using TBK1/NAK Antibody.

Background

TBK1 (TANK-binding kinase 1)/NAK (NF-κB activating kinase) is an IκB kinase (IKK)-activating kinase and can activate IKK through direct phosphorylation (1). TBK1 was identified through association with the TRAF binding protein, TANK, and found to function upstream of NIK and IKK in the activation of NF-κB (2). TBK1/NAK induces IκB degradation and NF-κB activity through IKKβ. NAK may mediate IKK and NF-κB activation in response to growth factors that stimulate PKCε activity (1). TBK1 plays a pivotal role in the activation of IRF3 in the innate immune response (3).
