在细胞的信号转导过程中,蛋白质中酪氨酸的磷酸化以及去磷酸化是非常重要的环节。这两种作用与酪氨酸磷酸酶(protein-tyrosine phosphatases,PTPs)去磷酸化作用和酪氨酸激酶(protein tyrosine kinases,PTKs)磷酸化作用密切相关。PTPs是将磷酸化信号分子的酪氨酸去磷酸化的激酶,
Phosphorylation of tyrosine and dephosphorylation of proteins in the cell’s signal transduction process is a very important link. These two effects are closely related to the dephosphorylation of protein-tyrosine phosphatases (PTPs) and the phosphorylation of tyrosine kinases (PTKs). PTPs are tyrosine-dephosphorylated kinases that phosphorylate signaling molecules,
