Actin
Definition
Actin is a protein that plays a key role in muscle contraction and cell movement.
Scientific / Technical Definition
Actin is a highly conserved protein found in all eukaryotic cells, forming filamentous structures that, together with myosin, are responsible for muscle contraction, motility, and the maintenance of cell shape. In muscle cells, actin filaments are part of the thin filament that interacts with myosin to produce muscle contractions through the sliding filament model.
Benefits
- Crucial for the mechanical support of cells.
- Facilitates movement in muscle cells.
- Involved in cell signaling pathways.
- Plays a role in cell division.
Examples
- Lean meats like chicken and turkey
- Fish and seafood
- Eggs
- Dairy products such as milk and cheese
Additional Information
- Importance: Actin is essential for cellular function, allowing for movement and stability within tissues, critical for processes like muscle contraction, and foundational in the skeletal structure of cells.
