Term

membrane raft

ID (Ontology)

GO:0045121 (Gene Ontology)

Definition

Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.[ PubMed:16645198 PubMed:20044567 ]

Also Known As

"lipid raft"
