Amino Acid Sequence

Cer-Glc-Gal(NeuAc)-GalNAc-Gal-NeuAc

General description

Gangliosides are in the neuronal cell membranes and endoplasmic reticulum. They consist of a sialylated polysaccharide chain linked via β-glycosidic linkage to ceramide. They are also located in body fluids and plasma. GD1a consists of a neutral tetrasaccharide core with one sialic acid on the internal galactose and another sialic acid on the non-reducing terminal galactose.

Application

Disialoganglioside GD1a from bovine brain has been used:
  • as a receptor for the detection of murine norovirus-1 (MNV-1) by RT-PCR
  • as a glycolipid to study the interaction between protein human endogenous retrovirus W family pHERV-W ENV and glycolipids by enzyme-linked immunosorbent assay (ELISA)
  • as a reference standard to analyze the ganglioside signatures of prostate cancer cells by high-performance liquid chromatography

Biochem/physiol Actions

Gangliosides are involved in cellular functions such as the differentiation of neurons, formation of axons, synapses, cell proliferation, differentiation, adhesion, and cell death. In addition, gangliosides form microdomains on the outer surface of the cell membranes that are involved in signal transduction and help in the formation of dendrites. Gangliosides act as Ca2+ binding co-factors during synaptic transmission.

Gangliosides are major cell-surface determinants in the central nervous system (CNS) of vertebrates, found both in neuronal and glial cell membranes. Together with cholesterol and glycosylphosphatidylinositol (GPI) - anchored proteins, gangliosides are involved in organization of plasma membrane microdomains. Based
