title: Filling gaps in signaling to actin cytoskeletal remodeling.
abstract: A recent publication in the April 4 issue of Cell advances our understanding of stimulus response coupling leading to actin remodeling. It describes the identification of a novel membrane component Mig-2 that engages filamin A through a new intermediary, migfilin, to stimulate actin assembly and cell spreading on a substrate of extracellular matrix.
