Signaling and myosin-binding protein C.
Myosin-binding protein C (MyBP-C) is a thick filament protein consisting of 1274 amino acid residues (149 kDa) that was identified by Starr and Offer over 30 years ago as a contaminant present in a preparation of purified myosin. Since then, numerous studies have defined the muscle-specific isoforms, the structure, and the importance of the proteins in normal striated muscle structure and funct...
متن کاملCardiac myosin binding protein C.
Myosin binding protein C (MyBP-C) is one of a group of myosin binding proteins that are present in the myofibrils of all striated muscle. The protein is found at 43-nm repeats along 7 to 9 transverse lines in a portion of the A band where crossbridges are found (C zone). MyBP-C contains myosin and titin binding sites at the C terminus of the molecule in all 3 of the isoforms (slow skeletal, fas...
متن کاملMyosin binding protein C in the heart.
Myocardial force generation is initiated on the release of calcium ions from the sarcoplasmic reticulum and subsequent activation of the contractile apparatus.1 A schematic of the cardiac sarcomere and some of its component proteins is shown in the Figure.2 Contractile activation involves binding calcium to Tn-C, redistribution of the affinity of Tn-I for Tn-C away from Tn-T, and movement of tr...
متن کاملCardiac myosin-binding protein-C phosphorylation and cardiac function.
The role of cardiac myosin binding protein-C (cMyBP-C) phosphorylation in cardiac physiology or pathophysiology is unclear. To investigate the status of cMyBP-C phosphorylation in vivo, we determined its phosphorylation state in stressed and unstressed mouse hearts. cMyBP-C phosphorylation is significantly decreased during the development of heart failure or pathologic hypertrophy. We then gene...

Backgroud: Protein-protein interaction, plays a key role in signal transduction in signaling pathways. Different approaches are used for prediction of these interactions including experimental and computational approaches. In conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins inter...
