Phospholipid phosphatase 6 (PLPP6) dephosphorylates presqualene diphosphate (PSQPP) to presqualene monophosphate (PSMP). It may be indirectly involved in innate immunity, as PSDP is a bioactive lipid that rapidly remodels to presqualene monophosphate PSMP upon cell activation. PLPP6 displays diphosphate phosphatase activity with a substrate preference PSDP > FDP > phosphatidic acid.
