WHAMM is a nucleation promoting factor. Depicted above is a pyrene actin polymerization assay performed with the following
reaction conditions 1: Actin + Arp2/3 + WHAMM (active isoform); 2-5: Actin + Arp2/3 + WHAMM (active isoform) and increasing
concentrations of Rab1; or 6: actin alone. What effect does Rab1 have on branched actin polymerization?
