Can proteins flip flop
WebFlippases are members of a larger family of lipid transport molecules that also includes floppases, which transfer lipids in the opposite direction, and scramblases, which randomize lipid distribution across lipid bilayers (as in apoptotic cells). WebProteins with a long intracellular domain may collide with a fence formed by cytoskeleton filaments. Both processes restrict the diffusion of proteins and lipids directly involved, as well as of other interacting components of the …
