The Batten disease protein CLN8 is a stereospecific acyltransferase in bis(monoacylglycero)phosphate biosynthesis
Loss-of-function mutations in the endoplasmic reticulum membrane protein CLN8 cause Batten disease, a neurodegenerative lysosomal storage disorder. CLN8 acts with the lysosomal enzyme CLN5 to produce bis(monoacylglycero)phosphate (BMP), a signature lysosomal phospholipid with unique S,S stereochemistry. However, the ro...
