In this study, we provide evidence that the cofilin phosphatase slingshot 1 like (SSH1L), an important regulator of the complex actin remodeling machinery, is a novel in vivo PKD substrate. PKD-mediated phosphorylation of serines 937 and 978 regulates SSH1L subcellular localization by binding of 14-3-3 proteins and thus impacts the control of local cofilin activation and actin remodeling during cell migration. In line with this, we show that the loss of PKD decreases cofilin phosphorylation, induces a more spread cell morphology, and stimulates chemotactic migration of breast cancer cells in an SSHL1-dependent fashion. Our data thus identify PKD as a central regulator of the cofilin signaling network via direct phosphorylation and regulation of SSH1L. %Z Peterburs, PhilippHeering, JohannaLink, GiselaPfizenmaier, KlausOlayioye, Monilola AHausser, AngelikaengResearch Support, Non-U.S. Gov'tCancer Res. 2009 Jul 15;69(14):5634-8. doi: 10.1158/0008-5472.CAN-09-0718.
