Membrane proteins that attach adjacent cells

WebProteins can associate with the membrane in one of three ways. Intrinsic or integral membrane proteins embed in the hydrophobic region of the lipid bilayer. Experimentally, these proteins can only be isolated by … WebMembrane proteins can serve a variety of key functions: Junctions – Serve to connect and join two cells together Enzymes – Fixing to membranes localises metabolic pathways Transport – Responsible for facilitated diffusion and active transport Recognition – May function as markers for cellular identification
