EXOSC3
This gene encodes a non-catalytic component of the human exosome, a complex with 3'-5' exoribonuclease activity that plays a role in numerous RNA processing and degradation activities. Related pseudogenes of this gene are found on chromosome 19 and 21. Alternatively spliced transcript variants encoding different isoforms have been described.

Interaction
Component of the RNA exosome complex (PubMed:29906447). Specifically part of the catalytically inactive RNA exosome core (Exo-9) complex which is believed to associate with catalytic subunits EXOSC10, and DIS3 or DIS3L in cytoplasmic- and nuclear-specific RNA exosome complex forms. Exo-9 is formed by a hexameric ring of RNase PH domain-containing subunits specifically containing the heterodimers EXOSC4-EXOSC9, EXOSC5-EXOSC8 and EXOSC6-EXOSC7, and peripheral S1 domain-containing components EXOSC1, EXOSC2 and EXOSC3 located on the top of the ring structure. Interacts with GTPBP1. Interacts with ZC3HAV1. Interacts with DDX17 only in the presence of ZC3HAV1 in an RNA-independent manner. Interacts with DHX36; this interaction occurs in a RNase-insensitive manner (PubMed:14731398). Interacts with HBS1L isoform 2 (PubMed:28204585).
