Abstract

Receptor tyrosine kinases (RTKs) are essential components of signal transduction pathways that mediate cell-to-cell communication. These single-pass transmembrane receptors, which bind polypeptide ligands - mainly growth factors - play key roles in processes such as cellular growth, differentiation, metabolism and motility. Recent progress has been achieved towards an understanding of the precise (and varied) mechanisms by which RTKs are activated by ligand binding and by which signals are propagated from the activated receptors to downstream targets in the cell.

摘要

受体酪氨酸激酶(RTKs)是介导细胞间通讯的信号转导通路的重要组成部分。这些单次跨膜受体可结合多肽配体——主要是生长因子——在细胞生长、分化、代谢和运动等过程中发挥关键作用。在理解RTKs通过配体结合被激活以及信号从激活的受体传递到细胞内下游靶点的精确(且多样)机制方面,已取得了最新进展。
