Meet Myosin Binding Protein C! Myosin Binding Protein C's childhood nickname was "C protein," but these days it goes by "MyBP-C." MyBP-C is a regulatory protein in muscle. As its name implies, it binds to myosin, which is the protein responsible for producing the force in a muscle contraction (meet myosin here!). It also binds …
Meet Myosin II!
Myosin II is a motor protein, which means it converts chemical energy into a mechanical response. Myosin II is a member of the myosin superfamily, and like its relatives, myosin II "walks" along tracks made of actin (learn about actin here). Myosin walks on actin. Myosin II is categorized as a muscle myosin because it …
