The biogenesis of Sm-type small nuclear ribonucleoproteins (snRNPs) involves the export of newly transcribed small nuclear RNAs… Expand Mass spectrometry was used to identify novel proteins associated with the human 17S U2 snRNP and one of its stable subunits, SF3b… Expand ABSTRACT Base pairing between U2 snRNA and the branchpoint sequence (BPS) is essential for pre-mRNA splicing. Because the… Expand Three viscoplastic approaches are examined in this paper. First, the overstress viscoplastic models (i.e. the Perzyna model and… Expand Splicing of mRNA precursors (pre-mRNAs) comprises a series of ATP-dependent steps, the first of which is the stable binding of U2… Expand A critical step in the pre-mRNA splicing reaction is the stable binding of U2 snRNP to the branchpoint sequence (BPS) to form the… Expand In characterizing a series of yeast (Saccharomyces cerevisiae) mutants synthetic lethal with U1 RNA, we have identified a yeast… Expand A protein of molecular size 62,000 daltons (p62) was detected in HeLa cell nuclear extracts by UV cross-linking to mRNA… Expand SV40 early pre-mRNA is alternatively spliced to produce large T and small t mRNAs by use of different 5'-splice sites and a… Expand Pre-mRNA splicing complex assembly is mediated by two specific pre-mRNA-snRNP interactions: U1 snRNP binds to the 5' splice site… Expand
