Postnatal Loss of Kindlin-2 Leads to Progressive Heart Failure.

ABSTRACT: The striated muscle costamere, a multiprotein complex at the boundary between the sarcomere and the sarcolemma, plays an integral role in maintaining striated muscle structure and function. Multiple costamere-associated proteins, such as integrins and integrin-interacting proteins, have been identified and shown to play an increasingly important role in the pathogenesis of human cardiomyopathy. Kindlin-2 is an adaptor protein that binds to the integrin β cytoplasmic tail to promote integrin activation. Genetic deficiency of Kindlin-2 results in embryonic lethality, and knockdown of the Kindlin-2 homolog in Caenorhabditis elegans and Danio rerio suggests that it has an essential role in integrin function and normal muscle structure and function. The precise role of Kindlin-2 in the mammalia
