Intracellular motility: myosin and tropomyosin in actin cable flow.
A new study has found that retrograde flow of budding yeast actin cables is facilitated by myosin II but is inhibited by a specific tropomyosin isoform (Tpm2p). Budding yeast therefore contains a minimal component system for elucidating the mechanistic details of retrograde actin flow.
