Tyrosine phosphorylation of proteins by protein tyrosine kinases (PTKs) is an important mechanism in the regulation of various cellular processes such as proliferation, differentiation, and transformation. Accumulating data implicate PTKs as essential intermediates in the transduction of extracellular signals to the interior of the cell. This review summarizes the mechanism of action of PTKs from the major subclasses and the involvement of PTK-encoding oncogenes in the regulation of hematopoietic cell function.
蛋白酪氨酸激酶(PTK)使蛋白质发生酪氨酸磷酸化,这是调控多种细胞过程(如增殖、分化和转化)的重要机制。越来越多的数据表明,PTK是细胞外信号转导至细胞内部的关键中间体。本文综述了主要亚类PTK的作用机制以及编码PTK的癌基因在造血细胞功能调控中的作用。
