Aktiinijärjestelmä
Aktiinijärjestelmä refers to the actin cytoskeleton in biology. It is a dynamic network of protein filaments within the cytoplasm of eukaryotic cells. These filaments are primarily composed of the protein actin. The actin cytoskeleton plays a crucial role in maintaining cell shape, enabling cell movement, and facilitating intracellular transport. It is involved in various cellular processes such as cell division, muscle contraction, and phagocytosis.
The actin cytoskeleton is organized into diverse structures, including microfilaments, stress fibers, lamellipodia, and filopodia. These
Cell motility is a key function facilitated by the actin system. Through processes like actin polymerization
Internal cellular organization and transport also rely on the actin system. It helps define cell polarity and
