| The LDL receptor is a polypeptide of 839 amino acids that spans the plasma membrane. |
| The resting potential is dependent upon ionic equilibria and the selective permeability of the plasma membrane. |
| These findings are supported by studies on the intracellular traffic between the Golgi apparatus and 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. |
| The catalytic domain faces the exterior of the plasma membrane and is anchored by a transmembrane-spanning domain. |
| In places the fine filaments run on top of the thicker filaments, and are thus closer to the plasma membrane. |
