Definitions for "Actin filament"
Protein filament, about 7 nm thick, formed from a chain of globular actin molecules. A major constituent of the cytoskeleton of all eucaryotic cells and especially abundant in muscle cells.
One of the contractile elements in muscular fibres and other cells; in skeletal muscle, the actin filament's are about 5 nm wide and 100 um long, and attach to the transverse Z filament's.
a polymer assembled from the protein actin (G-actin) via non-covalent interactions
