Actin is a globular protein that polymerizes to form long, thin filaments known as microfilaments, which are a key component of the cytoskeleton in eukaryotic cells. It plays a critical role in various cellular processes, including muscle contraction, cell shape maintenance, and cell motility. Actin exists in two forms: G-actin (globular actin) as a monomer and F-actin (filamentous actin) as a polymerized structure. Its dynamic nature allows for rapid assembly and disassembly, essential for cellular functions.
