Glycome Atlas
concept
Also known as lipid rafts, glycosphingolipid microdomains, membrane rafts
Plain-language answer
Cell membranes are not uniform. Cholesterol and sugar-bearing fats can gather into small, more ordered patches often called lipid rafts. These patches concentrate certain proteins and help organize signals at the cell surface.1
By clustering receptors together, raft-like domains influence how cells respond to signals, how some viruses and toxins enter, and how immune cells are activated.1
Technical detail
Glycosphingolipid- and cholesterol-enriched membrane microdomains laterally segregate proteins and glycolipids, providing platforms that modulate receptor clustering, signal transduction, and pathogen entry.1
Preferential packing of glycosphingolipids with cholesterol creates liquid-ordered regions that partition GPI-anchored proteins and select signaling components, concentrating them for efficient interaction.12
Raft-associated clustering influences immune receptor signaling and is exploited by certain toxins and viruses that use glycolipids as entry platforms.1
