Summary Introduction

To discuss:

Composition of a thin myofilament, the organization of its actin, tropomyosin, and troponin; and the active sites of its action monomers.

Introduction:

Thinfilaments, 7 nm in diameter, consist primarily of the protein actin, specifically fibrous (F) actin. Each F actin strand is composed of a string of subunits called globular (G) actin.
