    摘要： The invention discloses ten newly discovered PI3K regulatory subunit phosphorylation sites, tyrosines 467, 452, 463, and 470 in PI3KR1 (PI3Kp85 alpha), tyrosines 464, 460, and 467 in PI3KR2 (PI3Kp85 beta), and tyrosines 199, 184, and 202 in PI3KR3 (PI3Kp55 gamma), and provides reagents, including polyclonal and monoclonal antibodies, that selectively bind to PI3K when phosphorylated at one of the disclosed sites. Also provided are assays utilizing this reagent, including methods for determining the phosphorylation of PI3K in a biological sample, selecting a patient suitable for PI3K inhibitor therapy, profiling PI3K activation in a test tissue, and identifying a compound that modulates phosphorylation of PI3K in a test tissue, by using a detectable reagent, such as the disclosed antibody, that binds to PI3K only when phosphorylated at a disclosed site. The sample or test tissue may be taken from a subject suspected of having cancer, such as lymphoma, glioma, and colon cancer, involving altered PI3K signaling.
