Dynein actin

WebThus, cytoplasmic dynein, especially its 74-kD intermediate chain, is probably linked to its cargo through the p150 Glued –Arp1-actin short filament complex, and the binding of p150 Glued to Arp1 is mediated by dynamitin (23, 57, 58) (Fig. 5). WebJan 10, 2024 · The pivotal role of the actin network has been well studied. For example, membrane ruffling after MAF stimulation results from the local disruption of cortical F-actin filaments by ADF/cofilin family proteins, followed by actin re-polymerization by small GTPase, cdc42, and the actin nucleator Arp2/3 complex to form lamellipodia [6,7,8].
