Drosophila SNF is a member of the U1A/U2B″/SNF protein family that is found in U1 and U2 snRNPs, where it binds to Stemloop II and Stemloop IV of U1 and U2 snRNA, respectively. SNF also binds to the U2A' protein, but only in the U2 snRNP. Although previous reports have implicated U2A' as a necessary auxiliary protein for the binding of SNF to Stemloop IV, there are no mechanisms that explain the partitioning of U2A' to the U2 snRNP and its absence from the U1 snRNP. Using in vitro RNA binding… CONTINUE READING
