Alpha-actinin-3 also known as alpha-actinin skeletal muscle isoform 3 or F-actin cross-linking protein is a protein that in humans is encoded by the ACTN3 gene.Alpha-actinin is an actin-binding protein with multiple roles in different cell types. This gene expression is limited to skeletal muscle. It is localized to the Z-disc and analogous dense bodies where it helps to anchor the myofibrillar actin filaments.
