Supplementary information

Sarcomeric Alpha Actinin often referred to as alpha-actinin or A-actinin is a protein that functions mechanically as a cross-linker of actin filaments in the sarcomere. It plays a critical role in organizing the actin cytoskeleton providing structural integrity and facilitating muscle contraction. The protein typically has a molecular mass of approximately 100 kDa. It is expressed in a variety of tissues including skeletal and cardiac muscle where it establishes the architecture of the Z-disc by anchoring actin filaments.
Biological function summary

Sarcomeric alpha actinin associates with multiple proteins to form a complex that coordinates muscle function. It not only serves as a structural component but also participates in signaling processes influencing muscle repair and growth. Alpha actinin connects to other cytoskeletal proteins and adaptors coordinating with integrin pathways to transmit external mechanical signals into cellular responses. The ability of alpha actinin to interact with a range of proteins like filamin and spectrin enhances its role in maintaining cellular architecture.

Pathways

Alpha actinin is critical in both the integrin and dystrophin-glycoprotein complex pathways facilitating signal transduction and maintaining muscle stability. Its interaction with actin filaments is important for pathways involving cell adhesion and motility. Within these pathways actin-related proteins such as ACTN2 and titin partner with alpha actinin to sustain cellular structure and function during dynamic processes including muscle contraction and relaxation.

Mutations or defects in alpha actinin have implications in muscular dystrophy and cardiomyopathy. These conditions often involve disruptions in the muscle's structural framework and mechanical signaling where alpha actinin's interaction with dystrophin becomes significant. Additionally such disorders may showcase altered connectivity between alpha actinin and spectrin further affecting muscle integrity and function in pathological conditions.
