Phosphorylation at this site inhibits substrate binding and, thus, phosphatase activity in vitro, resulting in enrichment of phosphorylated cofilin in monolayer cell culture. We further demonstrate that protein kinase D (PKD) is upstream from Ser 402 phosphorylation. Accordingly, expression of active PKD in Drosophila phenotypically mimics the loss of SSH activity by inducing accumulation of phosphorylated cofilin and filamentous actin.
