Membrane Supply and Demand Regulates F-Actin in a Cell Surface Reservoir
详细信息    查看全文
文摘

Exocytosis adds membrane to a surface reservoir that unfolds to fuel furrow ingression

F-actin deforms the reservoir into dynamic microvilli that are lost as furrows ingress

Exocytosis (membrane supply) promotes microvillar F-actin assembly

Furrow ingression (membrane demand) promotes microvillar F-actin disassembly
