The activation of MP3K7(TAK1) by TAB1 activates NLK. the TAK1???NLK MAPK pathway regulates Wnt signaling by phosphorylating TCF in mammalian cells.
The TAB1 protein is a specific partner of TAK1 and promotes TAK1 autophosphorylation.
Coexpression of TAK1 and TAB1 in mammalian cells activate HIPK2, that activate NLK. THe coexpression of NLK and HIPK2 induces the degradation of the c-Myb protein.
Degradation of c-Myb protein by Wnt-1 signal via the pathway involving TAK1, HIPK2, and NLK leads to G1 arrest.

TAK1 activation stimulates NLK activity and downregulates transcriptional activation mediated by beta-catenin and TCF.
