Two pathways exist in mammalian cells to degrade 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate [PtdIns(4,5)P2] [2]. One is catalysed by this enzyme and the other by EC, phosphoinositide 5-phosphatase, where the product is PtdIns4P. The enzyme from human is specific for PtdIns(4,5)P2 as substrate, as it cannot use PtdIns(3,4,5)P3, PtdIns(3,4)P2, PtdIns(3,5)P2, PtdIns5P, PtdIns4P or PtdIns3P [2]. In humans, the enzyme is localized to late endosomal/lysosomal membranes [2]. It can control nuclear levels of PtdIns5P and thereby control p53-dependent apoptosis [3].
