Abstract

The mechanisms underlying the activity of non-receptor tyrosine kinase, TNK1, in cancers are unclear. Here the authors show that MARK mediates 14-3-3 and TNK1 interaction which restrains TNK1 activity, while the release of TNK1 from 14-3-3 leads to TNK1 activation through its interaction with ubiquitin and thus results in TNK1-mediated tumor growth in vivo
