Myosin thick filament
WebRT @raulpadron: We are excited to share our new reconstruction of the human cardiac thick filament C-zone, showing myosin heads, tails, titin and cMyBP-C at 6 Å resolution. WebFeb 10, 2024 · Like other enzymes in biology, the thick filament of the sarcomere is now thought to have at least an active and a dormant conformation of myosin. A dynamic equilibrium between these conformational states is believed to be essential to modulate the sarcomere contraction.

WebRT @raulpadron: We are excited to share our new reconstruction of the human cardiac thick filament C-zone, showing myosin heads, tails, titin and cMyBP-C at 6 Å resolution. WebMyosin is a thick filament composed of several polypeptide chains. The tail of each myosin molecule binds to other myosin molecules, forming the thick filament, while the heads project outward. Each myosin head contains an ATP binding site and an actin binding site. Actin is a thin filament composed of two strands of actin protein coiled together.

WebMyosin filaments, the thick filaments, are bipolar and extend throughout the A-band. They are cross-linked at the centre by the M-band. The giant protein titin (connectin) extends from the Z-line of the sarcomere, where it binds to the thick filament (myosin) system, to the M-band, where it is thought to interact with the thick filaments.
