WebThe cell cortex is attached to the inner cytosolic face of the plasma membrane in cells where the spectrin proteins and actin microfilaments form a mesh-like structure that is continuously remodeled by polymerization, depolymerization and branching. WebA common function of actin cytoskeletal structures is to stiffen or to change the shape of the plasma membrane. We have already encountered at least two examples: the spectrin-actin web that underlies the red blood …
