Lysyl-tRNA synthetase (KRS) interacts with the laminin receptor (LR/RPSA) and enhances laminin-induced cell migration in cancer metastasis. In this nuclear magnetic resonance (NMR)-based study, we show that the anticodon-binding domain of KRS binds directly to the C-terminal region of 37LRP, and the previously found inhibitors BC-K-01 and BC-K-YH16899 interfere with KRS-37LRP binding. In addition, the anticodon-binding domain of KRS binds to laminin, observed by NMR and SPR. These results provide crucial insights into the structural characteristics of the KRS-LR interaction on the cell surface.
赖氨酰 - tRNA合成酶（KRS）与层粘连蛋白受体（LR/RPSA）相互作用，并在癌症转移中增强层粘连蛋白诱导的细胞迁移。在这项基于核磁共振（NMR）的研究中，我们表明KRS的反密码子结合结构域直接与37LRP的C末端区域结合，并且先前发现的抑制剂BC - K - 01和BC - K - YH16899会干扰KRS与37LRP的结合。此外，通过NMR和SPR观察到，KRS的反密码子结合结构域与层粘连蛋白结合。这些结果为细胞表面KRS - LR相互作用的结构特征提供了关键见解。
