Which protein coats the inward-facing surface of the membrane and stabilises it during phagocytosis?

1. In preparation for phagocytosis, part of the inward-facing surface of the plasma membrane becomes coated with clathrin. 2. Clathrin stabilises that section of membrane so it can extend from the cell body and surround the particle. 3. Once the vesicle is enclosed, the clathrin disengages and the vesicle merges with a lysosome. 4. Caveolin is the coat protein used in potocytosis, and albumin and integrin have no coating role here. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 5 "Structure and Function of Plasma Membranes", section 5.4 Bulk Transport_
