Summary
Enables acyltransferase activity. Involved in phosphatidylinositol acyl-chain remodeling. Located in lipid droplet. Orthologous to human AGPAT3 (1-acylglycerol-3-phosphate O-acyltransferase 3); AGPAT4 (1-acylglycerol-3-phosphate O-acyltransferase 4); and LCLAT1 (lysocardiolipin acyltransferase 1).

NP_009598.1
  • Acyltransferase; enzyme mainly responsible for the introduction of saturated very long chain fatty acids into neo-synthesized molecules of phosphatidylinositol; required for incorporation of stearic acid into phosphatidylinositol; affects chromosome stability when overexpressed; CST26 has a paralog, YDR018C, that arose from the whole genome duplication
