471-596 3.03e-85

Domain of unknown function (DUF382); This domain is specific to the human splicing factor 3b subunit 2 and it's orthologues. Splicing factor 3b subunit 2 or SAP145 is a suppressor of U2 snRNA mutations. Pre-mRNA splicing is catalyzed by a large ribonucleoprotein complex called the spliceosome. Spliceosomes are multi-component enzymes that catalyze pre-mRNA splicing and form step-wise by the ordered interaction of UsnRNPs and non-snRNP proteins with short conserved regions of the pre-mRNA at the 5' and 3' splice sites and branch site.
