Beschreibung

Application

Useful for kinase assay.

Biochem/physiol Actions

Recombinant human PIP5K3 (1400-end) was expressed by Baculovirus in Sf9 insect cells using an N-terminal GST tag. PIP5K3 (also known as phosphatidylinositol-3-phosphate 5-kinase type III or PIPKIII) encodes an enzyme that phosphorylates the D-5 position in PtdIns and phospha-tidylinositol-3-phosphate (PtdIns3P) to make PtdIns5P and PtdIns (3,5)biphosphate. PIP5K3 belongs to a large family of lipid kinases that alter the phosphorylation status of intracellular phosphatidylinositol but also have protein kinase activity ⁽¹⁾. PIP5K3 regulate cytoskeletal functions, membrane trafficking, and receptor signaling by recruiting protein complexes to cell- and endosomal-membranes. The inhibition of PIP5K3 renders the late endosome /lysosome compartment refractory to fusion with autop-hagosomes and multivesicular bodies ⁽²⁾.
