最近的研究结果显着扩大了我们的理解,肌动蛋白解聚因子(ADF)/cofilin蛋白的调节和深刻的多方面的影响,这些完善的调节肌动蛋白动力学对细胞生物学。在这篇综述中,我们讨论了以前记录的调节,如磷酸化的新方面,但也涵盖了新的最近建立的调节模式和ADF(也称为destrin)/cofilin的新功能。我们现在了解到,它们的活性响应于大量的输入,远远大于以前的认识,这些蛋白质不仅反馈到肌动蛋白的至关重要的动力学,而且还凋亡级联,磷脂代谢和基因表达。我们认为,这种通过调节这些相同的变化来响应生理变化的能力使得ADF/cofilin蛋白家族成为细胞生物学中的稳态调节器或“功能节点”。
Recent findings have significantly expanded our understanding of the regulation of actin depolymerizing factor (ADF)/cofilin proteins and the profound multifaceted impact that these well-established regulators of actin dynamics have on cell biology. In this review we discuss new aspects of previously documented regulation, such as phosphorylation, but also cover novel recently established modes of regulation and new functions of ADF (also known as destrin)/cofilin. We now understand that their activity responds to a vast array of inputs far greater than previously appreciated and that these proteins not only feed back to the crucially important dynamics of actin, but also to apoptosis cascades, phospholipid metabolism, and gene expression. We argue that this ability to respond to physiological changes by modulating those same changes makes the ADF/cofilin protein family a homeostatic regulator or ‘functional node’ in cell biology.
