General Information
Term prominosome ID (Ontology) GO:0071914 (Gene Ontology)
Definition An extracellular membrane-bounded vesicle that contains prominin proteins (in mouse Prom1/CD33 or Prom2) and are found in body fluids including ventricular fluid, saliva, urine and seminal fluid. In the ventricular fluid of the developing mouse brain two major classes of these particles have been observed (P2 particles of 500-1000 nm and P4 particles of 50-80 nm) which likely originate from microvilli, primary cilia and/or the midbody of neuroepithelial cells. The physiological role is not known.[ PubMed:15976444 PubMed:17109118 PubMed:17283184 ]
Also Known As "prominin-containing extracellular membrane vesicle"
