肌球蛋白是基于肌动蛋白的运动蛋白,已知在细胞中执行各种不同的机械任务,包括运输货物、产生张力以及连接细胞骨架和膜。作为转运蛋白的肌球蛋白通常与接头蛋白和囊泡膜形成复合物,这使得人们不清楚它们如何通过肌动蛋白细胞骨架网络转运其货物。拉伊等人。现在使用单分子动力学、FRET 和模拟运动-适配器复合物的 DNA 折纸支架来揭示肌球蛋白 VI-Dab2 复合物,该复合物弱地结合在一起并快速翻转,可以在不破坏细胞骨架的情况下促进过程运输。
Myosins are actin-based motor proteins known to perform a variety of different mechanical tasks in cells including transporting cargo, generating tension, and linking the cytoskeleton and membrane. Myosins that function as transporters often form complexes with adaptor proteins and vesicular membranes, making it unclear how they transport their cargo through the actin cytoskeletal network. Rai et al. now use single-molecule kinetics, FRET, and DNA origami scaffolds that mimic motor–adaptor complexes to reveal that the myosin VI-Dab2 complex, which is held together weakly and turns over rapidly, can facilitate processive transport without disruption of the cytoskeleton.
