Description_x000D_ General description_x000D_ This Human VPS34 (vacuolar protein sorting 34) protein has a N-terminal FLAG-tag, expressed in Sf9 insect cells via a baculovirus expression system._x000D_ Application_x000D_ Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling._x000D_ Biochem/physiol Actions_x000D_ VPS34 was shown to be required for proper liver and heart function. Mice deficient in VPS34 develop hepatomegaly and cardiomegaly._x000D_ Unit Definition_x000D_ One unit will transfer one picomole of phosphate from ATP to a phospholipid mixture per minute at 30 °C at pH 7.4._x000D_ Physical form_x000D_ Formulated in a buffered solution consisting of 40 mM tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 80 μg/ml FLAG peptide, and 20% glycerol.
