Sphingolipids (SP) are one of the three major lipid classes in eukaryotic cells and serve as38
structural components of the plasma membrane. The rate-limiting step in SP biosynthesis is39
catalyzed by serine palmitoyltransferase (SPT). In yeast, SPT consists of two catalytic subunits40
(Lcb1 and Lcb2), a regulatory subunit (Tsc3), negative regulators (Orm1 and Orm2), and the41
