Intermediate structure called multi-vesicular body: when you form small vesicles within larger vesicular organelle: here membrane pinches in/ invaginates in, pinches off, & forms interluminal vesicles which may contain. As soon as they form, pm invaginates in & pinches off: once vesicles are formed, clathrin coat is shed and vesicle can fuse with early endosomes. Most of it faces the cytosol & inserted to pm. Much of proteins jets out into the cytosol: contents of endocytic compartments that come from pinching off (caveosomes) deposited to. Pm on opposite side of cell by process of transcytosis: difference b/w this form and 1st : clathrin coated pits are proteins that can be shut whereas.
