Function

Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha-actinin-1 is an F-actin cross-linking protein – a bundling protein that is thought to anchor actin to a number of intracellular structures. Alpha-actinin-1 is a non-muscle cytoskeletal isoform found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments.

• CDK5R1,
