What is Actin?
Actin is the name given to a group of protein molecules that bind together in muscle cells to form a thin band. In eukaryotes, the protein filament is in charge of forming the cellular cytoskeleton. It is further separated into monomeric and polymeric forms, known respectively as G-actin and F-actin. While F-actin is a filamentous actin protein, G-actin is a globular actin protein. These bands are essential for processes like cell migration, cytokinesis, and muscle contraction. Additionally, they support movement, communication, and maintaining the cell’s form.
Difference Between Actin and Myosin
The difference between actin and myosin lies in their structure and function within muscle cells. Actin forms thin filaments while myosin forms thick filaments, and together they interact for muscle contraction. Each type of muscle tissue contains the proteins myosin and actin. In this article, we will cover the difference between actin and myosin in detail.
