[Structure, function and modulation of actin-related protein 2/3 complex].
Microfilaments, composed of global actins, involve in many important physiological activities, such as the maintenance of cell shape and cell migration. Actin-related protein 2/3 ( Arp2/3) complex plays a key role in microfilament formation. Actin-related protein 2/3 ( Arp2/3 ) complex which is composed of seven different subunits is subjected to the modulation of many nucleation promoting factors (NPFs) and cooperates with these factors to regulate the actin nucleation. The study of the structure, function and modulation of Arp2/3 complex is important in understanding the mechanism of the formation of microfilament and the interaction between cytoskeleton and signaling molecules.
