Cytoplasmic exosome
WebJul 7, 2016 · The RNA exosome complex associates with nuclear and cytoplasmic cofactors to mediate the decay, surveillance, or processing of a wide variety of transcripts. In the cytoplasm, the conserved core of the exosome (Exo10) functions together with the conserved Ski complex. WebMar 20, 2024 · The ESCRT-II subunits can bind to RNA, and the ESCRT-machinery plays a crucial role in sorting the cytoplasmic mRNA and miRNA into exosomes . CD9, CD63, and CD81 proteins are enriched in exosomes, and thus, these proteins are considered to be markers for exosomes . In contrast to exosomes, microvesicles, whose diameters are …

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.
