Bradley, K. formins with multiple PI(4,5)P2 headgroups in the membrane to initiate actin nucleation. Masking PI(4,5)P2 with neomycin or disrupting PI(4,5)P2 domains in the plasma membrane by detatching cholesterol decreases the power of the membranes to nucleate actin set up in cytoplasmic ingredients. egg remove is enough to trigger actin assembly on the vesicle that […]
