aktiiniverkon
Aktiiniverkon, known in English as actin network or actin cytoskeleton, is a dynamic structure within eukaryotic cells. It is a complex of filamentous actin proteins that plays a crucial role in maintaining cell shape, enabling cell movement, and facilitating intracellular transport. Actin filaments, also called microfilaments, are thin, flexible rods that polymerize and depolymerize rapidly, allowing the network to constantly remodel.
This network is organized into various structures, including filopodia, lamellipodia, and stress fibers. Filopodia are finger-like
The formation and organization of the actin network are tightly regulated by a multitude of actin-binding proteins.
The actin network is fundamental to numerous cellular processes. It is involved in muscle contraction, where
