PIP3 86-90 phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit beta Homo sapiens 30-38 25544637-2 2015 This study reveals that, even among these sensitive cancers, the initial efficacy of p110alpha inhibition is mitigated by rapid re-accumulation of the PI3K product PIP3 produced by the p110beta isoform. PIP3 164-168 phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit beta Homo sapiens 185-193
