phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha/PI3-kinase p110-alpha subunit in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL4005] [GtoPdb: 2153] [UniProtKB: P42336] | ||||||||
ChEMBL | Enzyme Inhibition Assay: The PI3K enzymes catalyse the phosphorylation of phosphatidylinositol 4,5-biphosphate (PIP2) to phosphatidylinositol 3,4,5-triphosphate (PIP3) in the presence of ATP and Mg2+ ions. The PIP3 product can be detected by displacement of biotin-PIP3 from energy transfer complexes consisting of europium labelled anti-GST monoclonal antibody, a GST-tagged Pleckstrin homology (PH) domain, biotinylated PIP3 and streptavidin-allophycocyanin (APC) by the time-resolved fluorescence resonance energy transfer (TR-FRET) (HTRF PI3K enzyme assay, Millipore). Excitation, at 330 nm, of europium in the complex results in an energy transfer to the APC and a fluorescent emission at 665 nm although europium itself emits at its characteristic wavelength of 620 nm. The PIP3 product formed by PI3K activity displaces biotin-PIP3 from the complex and results in a loss of energy transfer (decreasing signal).The compound to be tested was added, at the desired final concentrations, to a mixture of PIP2 substrate. | B | 4.86 | pIC50 | >13900 | nM | IC50 | US-9227977-B2.
