Systematic name YMR165C
Gene name PAH1
Aliases SMP2
Feature type ORF, Verified
Coordinates Chr XIII:592628..590040
Primary SGDID S000004775


Description of YMR165C: Mg2+-dependent phosphatidate (PA) phosphatase; catalyzes dephosphorylation of PA to yield diacylglycerol; responsible for de novo lipid synthesis and formation of lipid droplets; phosphorylation by Pho80p-Pho85p decreases catalytic activity and alters Pah1p localization and abundance; phosphorylation by protein kinase A decreases catalytic efficiency; dephosphorylation by Nem1p-Spo7p anchors Pah1p to the membrane increasing substrate catalysis; homologous to mammalian lipin 1[1][2][3][4]
