Phosphatidate phosphatase APP1, catalytic domain This entry represents a conserved region found in Phosphatidate phosphatase APP1 from yeast, which contains the catalytic motif DXDX(T/V), present in other Mg+2-dependent phosphatases. This domain has a weak sequence similarity to the haloacid dehalogenase-like domain. APP1 catalyzes the dephosphorylation of phosphatidate to yield diacylglycerol and may play a role in vesicular trafficking through its phosphatidate phosphatase activity at cortical actin patches.
