Myosin VIII

Myosin VIII (a plant-specific myosin)
Page updated 2/4/02
A myosin that so far seems to be limited in its expression to the plants (Reddy et al, 2001). There the function of myosin VIII appears to be in the localization and transport of pre-cell wall vesicles at the phragmoplast upon cell division (Reichelt et al, 1999), and perhaps to regulate cytoplasmic flow between cells (Balsuska et al, 2001).
