- 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 - an overview | ScienceDirect Topics
Controlled polymerization of actin filaments (F-actin) from actin monomers (G-actin), regulated by numerous actin-binding proteins (ABPs), creates the foundation for the cytoskeleton and is essential for many cellular processes such as cell adhesion, cell motility and intracellular trafficking
- Actin: Anatomy and function | Kenhub
Actin exists in two forms: G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin) G-actin is responsible for the formation of the actin filament, while F-actin forms the cytoskeleton and contractile apparatus of muscle cells
- Actin: Structure, Function, and Dynamics - The Science Notes
Actin exists in two main forms: globular actin (G-actin) and filamentous actin (F-actin) G-actin is the monomeric, soluble form of the protein, while F-actin refers to the polymerized, filamentous structure
- Actin Protein: How It Builds, Moves, and Divides Cells
Actin is a highly abundant and fundamental protein found in nearly all eukaryotic cells, from yeast to humans It forms a versatile internal framework, often likened to a cellular “jack-of-all-trades,” supporting a wide array of life-sustaining processes
- PDB-101: Molecule of the Month: Actin
Actin filaments are continually built and broken down as the needs of the cell change from moment to moment In special cases, such as muscle actin or the actin bundles in microvilli, a collection of specialized actin-binding proteins stabilize the filament, forming a more permanent structure
- Actin Filaments - GeeksforGeeks
Actin filaments consist of globular actin (G-actin) subunits that polymerize into long, filaments that are parallel and helical This polymerised structure is known as filamentous actin (F-actin)
