Evidence that the 60-kDa protein of 17S U2 small nuclear ribonucleoprotein is immunologically and functionally related to the yeast PRP9 splicing factor and is required for the efficient formation of prespliceosomes.
Small nuclear ribonucleoprotein (snRNP) U2 functions in the splicing of mRNA by recognizing the branch site of unspliced mRNA. The binding of U2 snRNP and other components to pre-mRNA leads to the formation of a stable prespliceosome. In HeLa nuclear extracts, U2 snRNP exists either as a 17S form (u...
