And not only that, it also signals for the formation of a special type of protein layer protein covering around the vesicle. And the protein inside the covering is called clathrin. So that's exactly why this vesicle, once it's actually formed is called our clathrincoated vesicle. So the two main difference between phagocytosis and receptor mediated endocytosis is in our phagocyte. In our phagosone, we do not have our protein covering but in this case, we do have our protein covering. Now, in this case, the bacteria basically binds indirectly to the cell membrane.
