-The Exosome complex (or just- Exosome) is a multi-protein complex capable of degrading various types of RNA molecules. The Exosome complex is found in eukaryotic cell, and also in archaea, while in bacteria it is found as a simpler complex (but it has the same function). <ref>http://en.wikipedia.org/wiki/Exosome_complex#Structure</ref>

+Some of the exosome components are:<br />
+*'''MTR3''' and '''SKI6''' are part of RNase PH domain-containing subunits proposed to form a central channel which threads RNA for degradation.<br />
+*'''MTR4''' interacts with Nop53 and together they have a role in the maturation of 5.8S rRNA<ref>PMID:28883156</ref>.<br />
+*'''Rrp6''' is a nuclear-specific subunit promoting cell survival during heat stress<ref>PMID:32521279</ref>.<br />
+*'''Rrp44''' is the catalytic subunit <ref>PMID:19060898</ref>.<br />
+*'''Csl4''' is required for mRNA decay.<br />
+*'''M-phase phosphoprotein 6''' is involved in the 3'-processing  of the 7S pre-RNA to the mature 5.8S rRNA.
