摘要: A variety of growth factors and hormones mediate their cellular affects via interactions with cell surface receptors that possess protein kinase activity (Williams, 1989; Ullrich Schlessinger, 1990). The interaction most these ligands induces tyrosine activation autophosphorylation the receptor, resulting in physical association several cytoplasmic substrates having SH2 domains (Otsu et al., 1991; Skolnik 1991). Phosphoinositide 3-kinase (PI3K) has been identified through its ability to associate kinases, including numerous factor oncogene products
