Abstract
Single-molecule force spectroscopy and modeling have revealed that the adhesion molecule vinculin and F-actin form a catch bond that is dependent on the direction of forces along the actin filament. This may underlie the mechanisms by which cells sense directional physical cues.
摘要
单分子力谱学和建模研究表明，黏着斑蛋白 vinculin 和 F-肌动蛋白形成了一种依赖于肌动蛋白丝上力的方向的捕获键。这可能是细胞感知定向物理线索的机制基础。
