WebCoated vesicle definition, a clathrin-covered vesicle that forms from the closure of a coated pit, engulfing the ligand-receptor complex in endocytosis. See more. Some vesicles are made when part of the membrane pinches off the endoplasmic reticulum or the Golgi complex. Others are made when an object outside of the cell is surrounded by the cell membrane. The vesicle "coat" is a collection of proteins that serve to shape the curvature of a donor membrane, forming the rounded vesicle shape. Coat proteins can also function to bind to variou… WebFormation of the clathrin coated vesicle requires changes in membrane curvature, which is driven by PIP2 levels and BAR protein binding.
