Like microtubules, actin filaments have plus and minus ends, with more ATP-powered growth occurring at a filament's plus end (Figure 2). In many types of cells, networks of actin filaments are ...

These protrusive structures contain actin filaments, with elongating barbed ends orientated toward the plasma membrane. (B) During cellular arm extension, the plasma membrane sticks to the surface ...

Specifically, several biomolecular techniques were used to investigate the impact of CdSe/ZnS QDs on actin dynamics. Water-soluble CdSe/ZnS QDs coated with a carboxylic acid end group were ...
