The troponin complex and regulation of muscle contraction.

Abstract

In a wide variety of cellular settings, from organelle transport to muscle contraction, Ca2+ binding to members of the EF hand family of proteins controls the interaction between actin and different myosins that are responsible for generating movement. In vertebrate skeletal and cardiac muscle the Ca(2+)-binding protein troponin C (TnC) is one subunit of… (More)
