Descrizione generale

Myosin heavy chain (MHC) is a motor protein of muscle thick filaments. MHC regulates ultrastructural diversity of myofibrils.

Applicazioni

Myosin Heavy Chain from rabbit muscle has been used:
  • in SDS analysis of myosin heavy chain (MHC) composition and content
  • for microinjection into the outflow of heart (blood serum) and the cephalic cavities (embryonic cerebrospinal fluid) of chick embryo
  • as a muscle protein, to study the role of ascorbate as a facilitator of glycogen storage in muscles

Azioni biochim/fisiol

Molecular motor involved in the contraction of muscles.

Stato fisico

Solution in 50% glycerol containing 0.6 M KCl and 0.005 M potassium phosphate, pH 6.5

Myosin heavy chain (MHC) is the motor protein of muscle thick filaments. Most organisms produce many muscle MHC isoforms with temporally and spatially regulated expression patterns. This suggests that isoforms of MHC have different characteristics necessary for defining specific muscle

Cardiac contraction is triggered by the cyclic interaction of the "molecular motor" protein myosin with the actin filament, consuming ATP as the energy source to produce tension or shortening. The myosin heavy chain (MHC) contains the actin- and ATP-binding sites

Myosin

Myosins are a family of ATP-dependent motor proteins. Myosin II is the major contractile protein involved in eukaryotic muscle contraction by “walking” along actin microfilaments of the sarcomere
