sejtváz
Sejtváz, or the cytoskeleton, is the complex network of protein filaments inside eukaryotic cells that provides mechanical support, determines cell shape, and organizes the cytoplasm. It consists of three major classes of polymers: microfilaments (actin), intermediate filaments, and microtubules. In addition, cells can contain other filament systems and cross-linking proteins that modulate the network’s properties.
Microfilaments are flexible, about 7 nanometers in diameter, and are primarily built from actin monomers. They
The cytoskeleton is highly dynamic, with continuous polymerization and depolymerization influenced by cellular signaling and energy
Functions of the sejtváz include maintaining cell shape and mechanical integrity, organizing the cytoplasm, facilitating intracellular
