In yeast, actin forms patches associated with the plasma membrane. Patch distribution correlates with polarized growth during the cell cycle and in response to external stimuli. Using green fluorescent protein fused to capping protein to image actin patches in living cells, we find that patches move rapidly and over long distances. Even patches in clusters, such as at the incipient bud site, show movement. Patches move independently of one another and generally over small distances in a local area, but they can also move larger distances, including through the mother-bud neck. Changes in patch polarization occur quickly through the cell cycle. These observations provide important new parameters for a molecular analysis of the regulation and function of actin.
