- Actin | Definition Function | Britannica
actin, protein that is an important contributor to the contractile property of muscle and other cells It exists in two forms: G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin), the form involved in muscle contraction
- Actin Structure and Function - PMC
Actin is the most abundant protein in most eukaryotic cells It is highly conserved and participates in more protein-protein interactions than any known protein These properties, along with its ability to transition between monomeric (G-actin) and
- Actin, Myosin, and Cell Movement - The Cell - NCBI Bookshelf
Actin filaments, usually in association with myosin, are responsible for many types of cell movements Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement
- Actin and Myosin - Biology Dictionary
Actin and myosin are both proteins that are found in every type of muscle tissue Thick myosin filaments and thin actin filaments work together to generate muscle contractions and movement Myosin is a type of molecular motor and converts chemical energy released from ATP into mechanical energy
- Actin Filaments: Vital Roles and Regulation in Cell Biology
Actin filaments, also known as microfilaments, are integral to the cytoskeletal framework of eukaryotic cells These filaments are composed of actin, a globular protein that polymerizes to form long, thin helical structures
