Implication

Informs molecular mechanisms of muscle development; leaves open clinical translation to cardiomyopathies.

Key Points

To determine whether distinct populations of polysomes are responsible for synthesizing the individual light and heavy polypeptide chains of myosin.
Fractionated polyribosome populations isolated from muscle tissue to resolve translational complexes by size.
Assayed nascent protein chain synthesis associated with specific polysome fractions to identify active translation of myosin subunits.
Identified distinct, separate polysome classes uniquely engaged in the translation of either myosin light chains or heavy chains.
Demonstrated that myosin subunits are synthesized independently on discrete polysome populations rather than on a single polycistronic or shared assembly complex.
