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.

METTL4 catalyzes m6Am methylation in U2 snRNA to regulate pre-mRNA splicing
bioRxiv, 2020 N6-methylation of 2’-O-methyladenosine (Am) in RNA occurs in eukaryotic cells to generate N6,2’-O-dimethyladenosine (m6Am). Identification of the methyltransferase responsible for m6Am catalysis has accelerated studies on the function of m6Am in RNA ...

Recurrent noncoding U1 snRNA mutations drive cryptic splicing in SHH medulloblastoma
Nature, 2019 In cancer, recurrent somatic single-nucleotide variants—which are rare in most paediatric cancers—are confined largely to protein-coding genes1–3. Here we report highly recurrent hotspot mutations (r.3A>G) of U1 spliceosomal small nuclear RNAs (snRNAs ...

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.

U2 snRNA structure is influenced by SF3A and SF3B proteins but not by SF3B inhibitors.
PLoS ONE, 2021 U2 snRNP is an essential component of the spliceosome. It is responsible for branch point recognition in the spliceosome A-complex via base-pairing of U2 snRNA with an intron to form the branch helix.

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 ...

Isolation of Nuclei from Human Snap-frozen Liver Tissue for Single-nucleus RNA Sequencing
Bio-Protocol, 2023 Single-nucleus RNA sequencing (snRNA-seq) provides a powerful tool for studying cell type composition in heterogenous tissues. The liver is a vital organ composed of a diverse set of cell types; thus, single-cell technologies could greatly facilitate the

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]
, 2014 There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.
