| Outline of Final Research Achievements |
Bis(monoacylglycero)phosphate (BMP) is a unique phospholipid enriched in the late endosome. There are some questionable points about the function of BMP and the de novo biosynthesis of BMP has not been clearly demonstrated. In this study, I tried to identify a novel enzyme gene involved in the BMP biosynthesis and establish a cell line that the amount of BMP is decreased by silencing of the gene.
From the result of proteome analysis of endosome, I found some acyltransferases and some phospholipases which may be involved in the BMP biosynthesis. Gene silencing indicated that one of the phospholipases was involved in the BMP biosynthesis. Finally I succeeded to establish the cell line the amount of BMP is decreased by silencing of the gene.
