title: Cell polarity: formin on the move.
abstract: Formins assemble actin filaments that are typically arranged in long bundles. A new study has discovered that a fission yeast polarity formin transiently assembles short actin filaments at the cell tip, and then releases from the cortex and rides into the cell interior on filaments within the bundle.
