Unformatted text preview: ific proteins binding receptors Fig. 2-6 Fig. 2-7 CV coated w/ clathrin, later clathrin is released and recycled. forms vesicle w/ fluid INSIDE. transmembrane proteins act as receptors! Receptors can move laterally, they cluster together to form CV. ^^ all these directed by cytoskeleton in cell! Receptor-mediated endocytosis allows maximal control of the process. Peripheral membrane proteins, including clathrin, cause formation of coated pits, budding inward as coated vesicles (CV). These then fuse as endosomes, which may later fuse with various cytoplasmic organelles as directed by their surface proteins. Clathrin binds to inside of cell membrane -- forms COATED PIT, which become coated vesicles. Ribosomes, polyribosomes, and rough endoplasmic reticulum (RER) many bound to surface of MEMBRANEOUS NETWORK. Called Endoplasmic Reticulum. RER in green here e- dense areas = black = ribosomes Fig. 2-10 some ribosomes FREE in cytoplasm Polysomes are ribosomes on mRNA and have two general locations in the cell. They may be free in the cytoplasm (left), making cytoplasmic proteins (or proteins to be imported into the nucle...
