Abstract

Compensatory endocytosis retrieves membrane and proteins that are deposited at the plasma membrane during exocytosis. A new study reveals that actin filaments assemble into structures that compress membrane-bound endocytic compartments formed after exocytosis. This suggests that compressive forces generated by actin polymerization might remodel membranes during secretory and endocytic traffic.
