Protein

CDP-diacylglycerol--inositol 3-phosphatidyltransferase

Gene
CDIPT, PIS, PIS1
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the biosynthesis of phosphatidylinositol (PtdIns) as well as PtdIns:inositol exchange reaction. May thus act to reduce an excessive cellular PtdIns content. The exchange activity is due to the reverse reaction of PtdIns synthase and is dependent on CMP, which is tightly bound to the enzyme.1 Publication

Catalytic activityi

CDP-diacylglycerol + myo-inositol = CMP + phosphatidyl-1D-myo-inositol.1 Publication

Cofactori

Divalent metal cations; Mn2+ or Mg2+.1 Publication

Enzyme regulationi

Inhibited by PtdIns (product inhibition), phosphatidylinositol phosphate, and nucleoside di- and tri-phosphates.

pH dependencei

Optimum pH is 9.0.1 Publication

Temperature dependencei

Optimum temperature is 50 degrees Celsius.
