| The catalytic domain faces the exterior of the plasma membrane and is anchored by a transmembrane-spanning domain. |
| The resting potential is dependent upon ionic equilibria and the selective permeability of the plasma membrane. |
| The additional membrane is provided by intracellular vesicles, which fuse with the plasma membrane. |
| Vimentin fibers terminate at the nuclear membrane and at desmosomes, or adhesion plaques, on the plasma membrane. |
| The LDL receptor is a polypeptide of 839 amino acids that spans the plasma membrane. |
| The antigen was more abundant in the zone adjacent to the plasma membrane than in the zone closer to the external wall surface. |
