Background Information

Transforming growth factor-β (TGF-β)-activated kinase 1 (TAK1), also known as MAP3K7 – mitogen-activated 

protein kinase kinase kinase 7 – is a serine/threonine protein kinase triggering phosphorylation of AMP-activated

 protein kinase (AMPK) and playing a role in the signal transduction of TGF-β, bone morphogenetic proteins 

(BMPs), and various proinflammatory mediators.

What is the molecular weight of TAK1? Are there any isoforms of TAK1?

The molecular weight of full-length TAK1 is 55 kDa. There are four splicing variants of TAK1. TAK1-B represents 

the full-length variant, while TAK1-A, TAK1-C, and TAK1-D lack exons 12 and/or 16. TAK-1 variants differ in their 

expression levels across tissues (PMID: 11118615).

Is TAK1 post-translationally modified?

TAK1 kinase activity is modulated by interacting with TAK1-binding proteins (TABs). Binding to TABs triggers 

autophosphorylation of TAK1 and depends on polyubiquitination of receptor-interacting protein 1 (RIP1) 

(PMID: 8638164 and 11460167). Additionally, TAK1 can be ubiquitinated, acetylated, and O-glycosylated, 

which impacts its activity (PMID: 28106845).

What is the subcellular localization of TAK1?

TAK1 is present in the cytoplasm.

What is the tissue expression pattern of TAK1?

TAK1 is ubiquitously expressed.

How can TAK1 activity be monitored?

TAK1 requires phosphorylation for its activity. TAK1 autophosphorylation in the presence of TBPs occurs on 

Thr178, Thr184, Thr187, and Ser192 residues. The most commonly used phosphorylation readout is Thr187
