COOH-terminal truncated cardiac myosin-binding protein C mutants resulting from familial hypertrophic cardiomyopathy mutations exhibit altered expression and/or incorporation in fetal rat cardiomyocytes.

Abstract excerpt

Mutations in human cardiac myosin-binding protein C (cMyBP-C) gene are associated with familial hypertrophic cardiomyopathy (FHC), and most of them are predicted to produce COOH-truncated proteins. To understand the molecular mechanism(s) by which such mutations cause FHC, we analyzed (i) the accumulation of human cMyBP-C mutants in fetal rat cardiomyocytes, and (ii) the protein sequence of the human wild-type...
