Activator Proteins for Glycosphingolipid Hydrolysis by Endoglycoceramidases
Endoglycoceramidase (EGCase) cleaves the linkage between oligosaccharides and ceramides of various glycosphingolipids (Ito, M., and Yamagata, T. (1986) J. Biol. Chem. 261, 14278-14282). Recently, by extensive purification, it was separated from cell-lytic factor (hemolysin) and found to consist of three molecular species each with its own specificity (EGCases I, 11, and 111) (Ito, M., and Yamag...
متن کاملAbnormalities of glycosphingolipid, sulfatide, and ceramide in the polycystic (cpk/cpk) mouse.
Polycystic kidney disease is a disorder marked by aberrant renal tubular epithelial cell proliferation and transport abnormalities. Sphingolipids are ubiquitous membrane components implicated in several cellular functions including cell membrane sorting, signaling, growth, ion transport, and adhesion. To investigate a potential pathogenic role for sphingolipids in cystic kidney disease, we stud...
متن کاملThe possible contribution of a general glycosphingolipid transporter, GM2 activator protein, to atherosclerosis.
We previously found that oxidized low-density lipoprotein (LDL) elevated the expression of mRNA of GalNAcbeta1-4[NeuNAcalpha2-3]Galbeta1-4Glc-Cer (GM2) ganglioside activator protein, in human monocyte-derived macrophages. Recently, GM2 activator protein has become known as a general glycosphingolipid transporter as well as a specific cofactor for the hydrolysis of GM2 ganglioside by lysosomal b...
متن کاملThe glycosphingolipid sulfatide in the islets of Langerhans in rat pancreas is processed through recycling: possible involvement in insulin trafficking.
In previous studies we have shown that sulfatide (galactosylceramide-3-O-sulfate), in various species, is present in the insulin-producing cells in pancreatic islets of Langerhans. In this study the synthesis of sulfatide in the islets has been investigated by pulse chase labeling at varying glucose levels and in the presence or absence of the glycosphingolipid synthesis inhibitory agents, Bref...
