Immunopharmacology Comments
TAOK1 has been discovered to function as a negative regulator of IL-17 (IL-17A)-mediated signal transduction and inflammation [8]. IL-17 is a proinflammatory cytokine involved in the development of several autoimmune diseases, including inflammatory bowel disease and Sjögren's syndrome. TAOK1 appears to interact with IL-17RA, and this action prevents IL-17RA-Act1-TRAF6 signaling complex formation, and inhibits NF-κB and MAP kinase pathway activation. This in turn leads to a reduction in the expression of IL-17-induced proinflammatory mediators (e.g. IL-6, CXCL1, CXCL2, CCL20 and CSF3). TAOK1 is revealed as a component of the regulatory system that controls IL-17activity that is necessary to limit harmful IL-17-driven inflammation and autoimmune disease. Decreased TAOK1 expression has been reported in the colons of ulcerative colitis patients. Thus, the accumulating evidence delineating TAOK1 's functions indicate that this kinase is involved in the pathogenesis of IL-17-related autoimmune conditions.
Physiological Consequences of Altering Gene Expression
Taok1-deficient mice are more sensitive to TNBS-induced inflammatory bowel disease (IBD) than wild-type mice.
Species:  Mouse
Tissue: 
Technique:  Conditional knockout by crossing Taok1fl/fl mice with Pvillin-Cre transgenic mice to generate with Taok1 deletion specifically in intestinal epithelial cells.
References:  8
Overexpression of TAOK1 in HeLa cells downregulates IL-17-induced phosphorylation of NF-&kapp;B and MAPK kinases (i.e. TAOK1 inhibits the IL-17 signaling pathway).
Species:  Human
Tissue:  HeLa cells.
Technique:  Transient expression.
References:  8
General Comments
As well as being a member of the STE20-like kinases family, TAOK1 is also a member of the MAP kinase kinase kinase family, and is involved in MAPK signaling. It is reported to be involved in microtubule dynamics and mitotic progression [3], and the p38 and JNK response to DNA damage and stress stimuli [6].
