Gene Summary
Phosphatidylinositol synthase (Pis) encodes an enzyme involved in the synthesis of phosphatidyl inositol, which is further modified to give rise to phosphorylated membrane lipids with multiple functions. It is important for membrane composition and Pis mutants develop various cellular polarity abnormalities, e.g. epithelial cells will misposition basement membrane proteins at their apical side, due to a lack of PIP2.
