Activated CDC42 kinase 1 (TNK2)

Phosphorylates AKT1, AR, MCF2, WASL and WWOX. Implicated in trafficking and clathrin-mediated endocytosis through binding to epidermal growth factor receptor (EGFR) and clathrin.

Binds to both poly- and mono-ubiquitin and modulates ligand-induced degradation of EGFR, thereby leading to the accumulation of EGFR at the limiting membrane of early endosomes. Downstream effector of CDC42 that mediates CDC42-dependent cell migration via phosphorylation of BCAR1.
