abstract = {Gangliosides (GGs) are sialic acid-containing
glycosphingolipids (GSLs) and major membrane components
enriched on cellular surfaces. Biosynthesis of mammalian GGs
starts at the cytosolic leaflet of endoplasmic reticulum
(ER) membranes with the formation of their hydrophobic
ceramide anchors. After intracellular ceramide transfer to
Golgi and trans-Golgi network (TGN) membranes, anabolism of
GGs, as well as of other GSLs, is catalyzed by
membrane-spanning glycosyltransferases (GTs) along the
secretory pathway. Combined activity of only a few
promiscuous GTs allows for the formation of
cell-type-specific glycolipid patterns. Following an
exocytotic vesicle flow to the cellular plasma membranes,
GGs can be modified by metabolic reactions at or near the
cellular surface. For degradation, GGs are endocytosed to
reach late endosomes and lysosomes. Whereas
membrane-spanning enzymes of the secretory pathway catalyze
GSL and GG formation, a cooperation of soluble glycosidases,
lipases and lipid-binding cofactors, namely the sphingolipid
activator proteins (SAPs), act as the main players of GG and
GSL catabolism at intralysosomal luminal vesicles (ILVs).},
