Mechanisms of the RNA helicases DDX42 and DDX46 in human U2 snRNP assembly [PDF]
Nature Communications, 2023 The U2 snRNP recognizes the intron during spliceosome assembly. Here the authors report the high-resolution structures of two assembly precursors of human U2 snRNP and reveal that the RNA helicases DDX42 and DDX46 are mutually exclusive in terms of SF3B1-

The Challenge of Viral snRNPs [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2006 Some gammaherpesviruses encode nuclear noncoding RNAs (ncRNAs) that assemble with host proteins. Their conservation and abundance implies that they serve important functions for the virus. This paper focuses on our studies of three classes of nuclear noncoding herpesvirus RNAs.

Principles and correction of 5’-splice site selection
RNA Biology, 2022 In Eukarya, immature mRNA transcripts (pre-mRNA) often contain coding sequences, or exons, interleaved by non-coding sequences, or introns. Introns are removed upon splicing, and further regulation of the retained exons leads to alternatively spliced ...

Structural basis for dual roles of Aar2p in U5 snRNP assembly [PDF]
, 2013 Yeast U5 small nuclear ribonucleoprotein particle (snRNP) is assembled via a cytoplasmic precursor that contains the U5-specific Prp8 protein but lacks the U5-specific Brr2 helicase.

USP15 regulates dynamic protein-protein interactions of the spliceosome through deubiquitination of PRP31. [PDF]
, 2017 Post-translational modifications contribute to the spliceosome dynamics by facilitating the physical rearrangements of the spliceosome. Here, we report USP15, a deubiquitinating enzyme, as a regulator of protein-protein interactions for the spliceosome ...

LARP7 suppresses P-TEFb activity to inhibit breast cancer progression and metastasis. [PDF]
, 2014 Transcriptional elongation by RNA polymerase (Pol) II is essential for gene expression during cell growth and differentiation. The positive transcription elongation factor b (P-TEFb) stimulates transcriptional elongation by phosphorylating Pol II and ...

PRP4: a protein of the yeast U4/U6 small nuclear ribonucleoprotein particle [PDF]
, 1989 The Saccharomyces cerevisiae prp mutants (prp2 through prp11) are known to be defective in pre-mRNA splicing at nonpermissive temperatures. We have sequenced the PRP4 gene and shown that it encodes a 52-kilodalton protein.

Interaction of yeast eIF4G with spliceosome components Implications in pre-mRNA processing events [PDF]
, 2009 International audienceAs evidenced from mammalian cells the eukaryotic translation initiation factor eIF4G has a putative role in nuclear RNA metabolism. Here we investigate whether this role is conserved in the yeast Saccharomyces cerevisiae.
