WebEach exosome contains various cytoplasmic and membrane proteins in addition to lipids and RNA molecules. These components vary according to the exosome’s cell of origin. Exosomes are present in body fluids such as blood, urine, saliva, amniotic fluid, and malignant ascites. WebThe yeast RNA exosome consists of a highly conserved 9-subunit core complex and two catalytic subunits, Rrp44 and Rrp6. Rrp44 is bound with exosome core both in cytoplasm and nucleus, while Rrp6 is unique in nucleus. The yeast cytoplasmic exosome has a Ski7 protein that bridges the complex to Ski complex for degradation of aberrant mRNAs.
