Involved in cytoskeletal organization and cellular growth. May exert its effects on the cytoskeleton directly, or indirectly via proline-binding proteins such as profilin or proteins possessing SH3 domains. Plays a role in actin patch assembly by enhancing the ability of myo1 to stimulate actin polymerization by the Arp2/3 complex. Interacts with wsp1. Interacts with myo1 (via SH3 domain). Interacts with actin monomers. Localized to patches at the tips of growing interphase cells. These patches form prior to patches of myo1, but in cells lacking myo1, they are less intense and may be short lived. Detected in the medial region of mitotic cells, and this requires cdc15. Grows normally at 25 degrees Celsius. Displays morphological defects at high temperatures and is cold sensitive. At 18 degrees Celsius, becomes rounded, characteristic of a polarity defect. Synthetically lethal with deletion of myo1. Belongs to the verprolin family.
