TBK1 Assay – Transcreener Application

Learn More About Transcreener Method Used for This TBK1 Assay

TBK1 Assay - A Transcreener ADP2 Assay Application

Transcreener ADP² Kinase Assay directly measures the ADP produced by TBK1 (Tank Binding Kinase 1). These ADP measurements allow researchers to effectively determine the activity of the TBK1 enzyme. The assay provides a powerful tool to screen compound libraries for TBK1 modulators to help find new therapies for disease. 

The kit comes complete with the detection reagents required to measure activity. TBK1 enzyme is not included in the inhibitor screening assay kit. Please contact us for questions related to acquiring the enzyme. 

This assay is designed to be used with purified enzyme preparations. Transcreener assays are not validated with cell lysates, blood, serum, or other biological samples.

How Does This TBK1 Assay Work?

The Transcreener TBK1 Assay determines TBK1 enzyme activity by directly measuring the ADP formed by the enzyme using the Transcreener ADP Assay. By detecting ADP output, the assay provides a universal method to assess the activity of any ADP-producing enzyme in real-time. 

Transcreener TBK1 Assay technology uses a simple but highly effective method that consists of an antibody selective to ADP over ATP and a far-red fluorescent tracer. ADP produced in the reaction competes with the tracer changing the fluorescent properties and providing fluorescent readout. 

The TBK1 assay is available with FP, FI, and TR-FRET. It is a simple mix-and-read format. Perform your enzyme reaction, add the detection reagent, and measure. The simplicity of the system yields robust results that also makes it extremely amiable to HTS.

Transcreener Mix and Read Assay

Robust Assay Yields Quality Data

Z’ measurements using optimized TBK1 reaction conditions indicate a robust assay.  Robust data like this is vital for sizeable high throughput screens that are difficult to complete due to massive sample quantity. Z' shown here = 0.74.

Detection of ADP Under TBK1 Initial Velocity

The assay demonstrates linearity when raw data is converted to ADP using a standard curve. Many TBK1 interactions are currently known including phosphorylation of IRF3 and IRF7. Here we use both 10 µM ATP with 25 µM CK1tide peptide substrates. Linearity is shown here under initial velocity conditions when raw data is converted to ADP formed. Non-productive hydrolysis of ATP occurs in many kinase reactions due to many factors including autophosphorylation and water exploiting the ATP binding pocket of the enzyme.

DNA Damage Response and Innate Immunity Preview

The Role of TBK1 As a Therapeutic Target

TBK1 is studied for its innate immune response to foreign infections. Toll-like receptors activate TBK1 leading to further signaling. As a regulator of the immune response pathway to viral & bacterial material, TBK1 interacts with TANK and TRAF3. TBK1 phosphorylates interferon regulator factors (IRFs), activating inflammatory responses with type I IFNs.

TBK1’s role in inflammatory modulation makes it a critical target for autoimmune and neurodegenerative diseases. TBK1 also regulates aspects of cell proliferation and death, making it a key focus area in cancer research. The Transcreener ADP2 TBK1 Assay is an excellent tool for researchers examining the therapeutic effects of TBK1.
