Also known as actins, Actin family, Actin, IPR004000

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.

AI overview

Actin is a protein found in nearly all living cells that assembles into tiny filaments that make up part of the cell's internal structural framework and form the thin filaments in muscle tissue. Because actin is so abundant and versatile, it plays essential roles in cell movement, shape changes, and muscle contraction.
