Alpha-Actinin-3
Meaning
Alpha-Actinin-3 (ACTN3) is a structural protein in fast-twitch skeletal muscle fibers, crucial for contraction and force generation. Encoded by the ACTN3 gene, it stabilizes the sarcomere’s Z-disc. A common genetic polymorphism can lead to its complete absence in some individuals, impacting their muscle characteristics.
