Overview
ACTN2 F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein. Defects in ACTN2 are the cause of cardiomyopathy dilated type 1AA (CMD1AA). 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. Belongs to the alpha-actinin family. Note: This description may include information from UniProtKB.

Chromosomal Location of Human Ortholog: 1q42-q43
Cellular Component: focal adhesion; cytoskeleton; extracellular region; dendritic spine; actin filament; pseudopodium; Z disc; cytosol; filopodium
Molecular Function: integrin binding; protein dimerization activity; actin filament binding; identical protein binding; LIM domain binding; protein binding; structural constituent of muscle; cytoskeletal protein binding; titin binding; calcium ion binding; FATZ binding; thyroid hormone receptor coactivator activity
