Dysferlin is expressed in skeletal and cardiac muscle. However, dysferlin deficiency, namely limb girdle muscular dystrophy 2B (LGMD2B) and Myoshi myopathy, results in skeletal muscle weakness and spares the heart. This dichotomy could be caused by differential regulation of protective mechanisms. T...
BACKGROUND: Despite significant advances in acute care medicine, myocardial infarction (MI) remains a predominant cause of premature death and heart failure. In the infarct border zone, cardiomyocytes are exposed to high biomechanical stress that impairs the integrity of the sarcolemmal membrane. He...
By comparing the transcriptome from proximal (quadriceps femoris, QF) and distal (tibialis anterior, TA)muscle groups in dysferlin deficient mouse muscle (the SJL mutation bred onto C57BL/10 to produces C57BL/10.SJL_Dysf) with proximal and distal muscle groups from control C57BL/10 mice of an equiva...
Dysferlin is an essential muscle membrane repair protein and autosomal recessive mutations in its gene result in progressive muscular dystrophies collectively called dysferlinopathies. We previously showed that calpain-mediated cleavage within dysferlin exon 40a releases a 72kDa C-terminal minidysfe...

BACKGROUND: Cardiac hypertrophy compensates for increased biomechanical stress of the heart induced by prevalent cardiovascular pathologies, but can result in cardiac failure if left untreated. We hypothesized that the tail-anchored protein Dysferlin with multiple Ca2+-binding C2-domains is critical...

To explore the proteomic interactome of Dysferlin in the heart, we used recombinant expression of N-terminally Twin-Strep II-tagged full-length human Dysferlin to establish an in vitro binding assay. Isolated mouse heart membrane fractions were incubated with Dysferlin-coupled beads under four diffe...
