- 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 nm1. Actin exists in two forms: G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin), with the latter being involved in muscle contraction2.

Actin beta (HUGO Gene Nomenclature Committee abbreviation ACTB/ACTB) is one of six different actin isoforms which have been identified in humans. This is one of the two nonmuscle cytoskeletal actins. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of the contractile apparatus.
