| Scientific Background: | Myosin-binding protein 2 (cardiac type) (cMyBP-C) is a protein located in the C-zones of the A-band of the sarcomere and interacts specifically with myosin, titin and actin. Mutations in the human cMyBP-C gene are one of the most frequent causes of familial hypertrophic cardiomyopathy. cMyBP-C can be phosphorylated at three different sites by a cAMP-regulated protein kinase (PKA) and a Ca2+<-calmodulin kinase (CAMK) bound to the thick filament. The dephosphorylated form binds to the S2 subfragment of myosin whereas the phosphorylated form binds to actin. In solution, phosphorylation of cMyBP-C increases force of contraction, but both phospho- and dephosphorylated forms of cMyBP-C stimulate the actin-activated myosin ATPase activity. |
