Glucosylceramide synthase: assay and properties.
Glucosylceramide synthesis is a key step in the formation of most mammalian glycosphingolipids. The expanding number of cellular functions that may be glycosphinolipid dependent and the identification of this glucosylceramide synthase as a potential therapeutic target for several sphingolipid storage disorders necessitate the availability of a reliable assay for glucosylceramide synthase. Coupled with the recent sequencing of this enzyme, the liposome-based assay utilizing a single extraction step should aid in the understanding of this critical early pathway in glycosphingolipid formation.
