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.

Actin is a contractile protein fibers present in muscles.It occurs in two forms a.monomeric G actin b. polymeric F ACTIN.
The ball-shaped protein called actin is the primary component of microfilaments. Actin molecules polymerize to form thin, flexible filaments that are important for cell movement, shape, and division.

Actin and Myosin
Microfilaments are made of protein strands called actin.
The rope-like protein that passes through the MBS in G-actin is called F-actin. F-actin is formed by polymerization of G-actin subunits, creating a double helical structure that is essential for the structure and function of the cell's cytoskeleton.
