The ins and outs of sphingolipid synthesis
... LASS genes have been characterized, and each synthesizes dihydroceramide containing distinct fatty acids (Figure 3). When some of these genes were expressed in yeast defective in LAG1 and LAC1, they were able to reconstitute ceramide synthesis [33]. Ceramide synthase was recently purified in active ...
