Thin protein strand
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm. An actin protein is the monomeric subunit of two types of filaments in cells: micr… WebOct 4, 2024 · Thin filaments are composed of strands of the protein actin and a regulatory protein coiled together, whereas thick filaments are composed of strands of the protein myosin. The thin and thick filaments form partially overlapping layers that are laid out in functional units called sarcomeres.
