背景资料：Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. The tyrosine kinase (TK) group is mainly involved in the regulation of cell-cell interactions such as differentiation, adhesion, motility and death. There are currently about 90 TK genes sequenced, 58 are of receptor protein TK (e.g. EGFR, EPH, FGFR, PDGFR, TRK, and VEGFR families), and 32 of cytosolic TK (e.g. ABL, FAK, JAK, and SRC families).

文献和实验Assaying Tyrosine Phosphorylation of Insulin Receptor and Insulin Receptor Substrates
This chapter describes techniques to successfully detect tyrosine phosphorylation of the insulin receptor and insulin receptor substrate proteins. These assays demonstrate whether the insulin signaling pathway is activated at its earliest
胰岛素受体是一个四聚体，由两个α亚基和两个β亚基通过二硫键连接。两个α亚基位于细胞质膜的外侧，其上有胰岛素的结合位点；两个β亚基是跨膜蛋白，起信号转导作用。无胰岛素结合时，受体的酪氨酸蛋白激酶没有活性。当胰岛素与受体的α亚基结合并改变了β亚基的构型后，酪氨酸蛋白激酶才被激活，激活后可催化两个反应∶①使四聚体复合物中β亚基特异位点的酪氨酸残基磷酸化,这种过程称为自我磷酸化(autophosphorylation)；②将胰岛素受体底物(insulin receptor substrate

蛋白质,其上有多个(至少8个)可被受体激酶磷酸化的位点,磷酸化后可同多种效应物结合,包括:PI(3)K、Syp(一种磷酸酪氨酸磷酸酶)、Nck(一种连接蛋白)、GRB2(growth factor receptor-bound protein 2,一种通过SH2同磷酸化的酪氨酸结合的连接蛋白)。第二种是Shc(是通过cDNA克隆筛选到的编码SH结构域的基因的蛋白产物),也是一种连接蛋白。Shc的酪氨酸被磷酸化后能够同GRB2结合,然后激活Ras,触发细胞的增殖。第三种底物是IRS2。IRS2的酪氨酸被磷酸
