| Review Title: | Molecular impact of mutations in RNA splicing factors in cancer |
| Abstract: | Somatic mutations in genes encoding components of the RNA splicing machinery occur frequently in multiple forms of cancer. The most frequently mutated RNA splicing factors in cancer impact intronic branch site and 3' splice site recognition. These include mutations in the core RNA splicing factor SF3B1 as well as mutations in the U2AF1/2 heterodimeric complex, which recruits the SF3b complex to the 3' splice site. Additionally, mutations in splicing regulatory proteins SRSF2 and RBM10 are frequent in cancer, and there has been a recent suggestion that variant forms of small nuclear RNAs (snRNAs) may contribute to splicing dysregulation in cancer. Here, we describe molecular mechanisms by which mutations in these factors alter splice site recognition and how studies of this process have yielded new insights into cancer pathogenesis and the molecular regulation of splicing. We also discuss data linking mutant RNA splicing factors to RNA metabolism beyond splicing. |
