| 1312357 | EXOSC3 | exosome component 3 | 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 encod ing different isoforms have been described.

| 1312358 | Exosc3 | exosome component 3 | Predicted to enable RNA binding activity. Involved in isotype switching. Acts upstream of or within positive regulation of isotype switching. Predicted to be located in cytosol; euchromatin; and nuclear lumen. Predicted to be part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase com plex). Is expressed in several structures, including cerebral cortex; gonad; liver; metanephros; and muscle tissue. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 1B. Orthologous to human EXOSC3 (exosome component 3).
