Background
DIS3, also known as RRP44, is a conserved protein responsible for the core catalytic activities of the exosome complex, which degrades RNA (1-3). With two catalytic sites, DIS3 possesses both endoribonucleolytic and 3’-to-5’ exoribonucleolytic activity (2,4). It plays very diverse roles in RNA metabolism, including control of aberrant pre-mRNA turnover, gene expression, and RNA processing (5-9). DIS3 also plays a role in mitotic progression by helping form kinetochores (9,10). Additionally, DIS3 is implicated in antibody diversity by helping the exosome target activation-induced cytidine deaminase to the DNA strands in B cells. DIS3 and other exosome components are upregulated during V(D)J recombination and B cells in knockout mice are unable to develop past the pro-B cell stage (11,12). Mutations in the DIS3 gene have been well described in multiple myeloma (13,14).
