在横纹肌中,肌动蛋白细胞骨架分化成肌原纤维。肌动蛋白和肌球蛋白丝组织在肌节中,专门用于产生收缩力。具有均匀长度和极性的肌动蛋白丝的规则排列对于收缩功能是至关重要的。然而,横纹肌中肌节肌动蛋白丝的组装和维持机制尚未完全清楚。横纹肌肌动蛋白的实时成像显示,肌节肌动蛋白丝内的肌动蛋白亚基动态交换,而不改变整体肌节结构。肌动蛋白动力学的许多调节因子已被确定,这些调节因子的功能障碍通常导致肌原纤维结构的紊乱或肌肉疾病。因此,横纹肌肌动蛋白动力学的适当调节对于功能性肌原纤维的组装和维持至关重要。最近的研究表明,肌动蛋白动力学的增强剂和肌动蛋白丝的稳定剂对肌节肌动蛋白组织都很重要。进一步研究横纹肌肌动蛋白动力学的调控机制是理解肌原纤维发育和运作的关键。© 2010 Wiley-Liss公司。
In striated muscle, the actin cytoskeleton is differentiated into myofibrils. Actin and myosin filaments are organized in sarcomeres and specialized for producing contractile forces. Regular arrangement of actin filaments with uniform length and polarity is critical for the contractile function. However, the mechanisms of assembly and maintenance of sarcomeric actin filaments in striated muscle are not completely understood. Live imaging of actin in striated muscle has revealed that actin subunits within sarcomeric actin filaments are dynamically exchanged without altering overall sarcomeric structures. A number of regulators for actin dynamics have been identified, and malfunction of these regulators often result in disorganization of myofibril structures or muscle diseases. Therefore, proper regulation of actin dynamics in striated muscle is critical for assembly and maintenance of functional myofibrils. Recent studies have suggested that both enhancers of actin dynamics and stabilizers of actin filaments are important for sarcomeric actin organization. Further investigation of the regulatory mechanism of actin dynamics in striated muscle should be a key to understanding how myofibrils develop and operate. © 2010 Wiley-Liss, Inc.
