MEMBRANE MOTILITY MEDIATED BY UNCONVENTIONAL MYOSIN

Largely on the basis of their physical properties and their localizati on to cell membranes, it has been proposed that the unconventional myo sins are membrane motors. In the past year, a combination of immunolog ical, biochemical and genetic approaches has begun to provide direct e vidence that unconventional myosins have important roles in movements of the plasma membrane and cytoplasmic organelles.
