aktiinimonomerejä
Aktiinimonomerejä, also known as G-actin, are globular protein subunits that polymerize to form filamentous actin, or F-actin. These monomers are essential components of the cytoskeleton in eukaryotic cells, playing crucial roles in cell shape, movement, and intracellular transport. Each actin monomer is approximately 42 kDa in size and possesses a binding site for ATP.
The polymerization process of G-actin into F-actin is a dynamic and reversible event. In the presence of
The binding of ATP to G-actin is critical for polymerization. Once incorporated into the filament, ATP is
Actin filaments are highly versatile and interact with a variety of actin-binding proteins (ABPs) that regulate
