How do proteins anchor in the membrane
WebThe membrane physically moves the molecules. Transport proteins move the molecules, so no energy is required. The concentration gradient drives the movement. The concentration gradient drives the movement. Once equilibrium is reached, the membrane permits all molecules to freely move across the membrane. WebLipid-anchored proteins reach the plasma membrane by following the secretory pathway out of the ER. One or two other cysteine residues upstream of the CAAX motif of N-Ras and H-Ras can be tagged with palmitic acid via a labile thioester bond. View chapter Purchase book Membrane Proteins
