古德和他的同事回顾了我们目前对细胞机制和驱动肌动蛋白网络重塑、分解和周转的机制的理解。细胞肌动蛋白网络表现出广泛的大小、形状和结构,以适应其生物学作用。一旦组装,这些丝状网络要么保持在极化翻转状态,要么被诱导进行网络拆卸。此外,网络移交和/或拆除的速度可能相差很大,从几秒钟到几分钟到几小时甚至几天。在这里,我们回顾了细胞中驱动肌动蛋白网络分解和周转的分子机械和机制。特别地,我们强调了最近的发现,表明保守的肌动蛋白分解促进蛋白(cofilin, GMF, twinfilin, Srv2/CAP, coronin, AIP1, capping protein和profilin)的特定组合协同工作,使肌动蛋白丝分离,切断,帽化和解聚合,并为新一轮的组装补充肌动蛋白单体。
Goode and colleagues review our current understanding of the cellular machinery and mechanisms driving actin network remodeling, disassembly, and turnover. Cellular actin networks exhibit a wide range of sizes, shapes, and architectures tailored to their biological roles. Once assembled, these filamentous networks are either maintained in a state of polarized turnover or induced to undergo net disassembly. Further, the rates at which the networks are turned over and/or dismantled can vary greatly, from seconds to minutes to hours or even days. Here, we review the molecular machinery and mechanisms employed in cells to drive the disassembly and turnover of actin networks. In particular, we highlight recent discoveries showing that specific combinations of conserved actin disassembly-promoting proteins (cofilin, GMF, twinfilin, Srv2/CAP, coronin, AIP1, capping protein, and profilin) work in concert to debranch, sever, cap, and depolymerize actin filaments, and to recharge actin monomers for new rounds of assembly.
