Abstract
Cofilin is a key regulator of actin cytoskeletal dynamics whose activity is controlled by phosphorylation of a single serine residue. We report the biochemical isolation of chronophin (CIN), a unique cofilin-activating phosphatase of the haloacid dehalogenase (HAD) superfamily. CIN directly dephosphorylates cofilin with high specificity and colocalizes with cofilin in motile and dividing cells. Loss of CIN activity blocks phosphocycling of cofilin, stabilizes F-actin structures and causes massive cell division defects. Our findings identify a physiological phospho-serine protein substrate for a mammalian HAD-type phosphatase and demonstrate that CIN is an important novel regulator of cofilin-mediated actin reorganization.
