title: Double JMY: making actin fast.
abstract: The assembly of actin networks is dependent on nucleation-promoting factors. A new study identifies JMY as a protein containing two separate nucleation-promoting activities that shuttles between the nucleus and the cytoplasm and promotes cell migration. These observations indicate that JMY is an important factor controlling actin dynamics in motile cells.
