[https://www.uniprot.org/uniprot/ACTN2_HUMAN ACTN2_HUMAN] Defects in ACTN2 are the cause of cardiomyopathy dilated type 1AA (CMD1AA) [MIM:[https://omim.org/entry/612158 612158]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.<ref>PMID:14567970</ref>

== Function ==

[https://www.uniprot.org/uniprot/ACTN2_HUMAN ACTN2_HUMAN] F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein.

We have determined the crystal structure of the two central repeats in the alpha-actinin rod at 2.5 A resolution. The repeats are connected by a helical linker and form a symmetric, antiparallel dimer in which the repeats are aligned rather than staggered. Using this structure, which reveals the structural principle that governs the architecture of alpha-actinin, we have devised a plausible model of the entire alpha-actinin rod. The electrostatic properties explain how the two alpha-actinin subunits assemble in an antiparallel fashion, placing the actin-binding sites at both ends of the rod. This molecular architecture results in a protein that is able to form cross-links between actin filaments.
