Exosome complex exonuclease RRP44, or Dis3, is an enzyme that in humans is encoded by the DIS3 gene. Its protein product is an RNase enzyme homologous to the yeast protein Rrp44, and can be part of the exosome complex in the nucleus of eukaryotic cells. By genomic sequence analysis, this gene is mapped to chromosome 13q21-q22. Expression of human DIS3 could partially complement Dis3 depletion in yeast.
