Max Planck scientists bring the basis of muscle movement into sharper focus Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical models have in fact described exactly how these muscle proteins interact, this interaction has never previously been observed in detail. Stefan Raunser and Elmar Behrmann from the Max Planck...

New research sheds light on the interaction between the semi-flexible protein tropomyosin and actin thin filaments. The study, published by Cell Press on February 15th in the Biophysical Journal, provides the first detailed atomic model of tropomyosin bound to actin and significantly advances the understanding of the dynamic relationship between these key cellular proteins. Tropomyosin is a long protein that associates with actin, a highly conserved thin filament protein found in organisms...
