(Submitter supplied) We isolated snRNP complexes derived from precatalytic A or B-like spliceosomes solubilized from the chromatin pellet of lysed nuclei. These complexes contained U2 snRNP proteins and a portion of the U2 snRNA, bound with intronic branch sites prior to the first catalytic step of splicing. The complexes have similar composition, whether directly isolated from extracted material, or after selection from glycerol gradients. more...

(Submitter supplied) RBM5 and RBM10 are RNA-binding proteins and splicing regulators. These two proteins are putative paralogs in mammalian cells, sharing common domain organization and extensive protein sequence similarity, but their RNA-binding preferences differ. We developed a sensitive system to identify splicing events regulated by RBM5 and/or RBM10, deleting all RBM5 alleles in 293Flp-In cells, and reducing the expression of RBM10, which is partially rescued by activation of a cryptic exon (CE) in one of the RBM10 alleles. more...

(Submitter supplied) In eukaryotes, a dynamic ribonucleic protein machine known as the spliceosome catalyzes the removal of introns from pre-messenger RNA (pre-mRNA). Recent studies show the process of RNA-synthesis and RNA-processing to be spatio-temporally coordinated, indicating that RNA splicing takes place in the context of chromatin. H2A.Z is a highly conserved histone variant of the canonical histone H2A. In S. cerevisiae, H2A.Z is deposited into chromatin by the SWR1-complex, is found near the 5’ ends of protein-coding genes, and has been implicated in transcription regulation. more...

(Submitter supplied) Transcription by RNA polymerase II (Pol II) is coupled to pre-mRNA splicing, but the underlying mechanisms remain poorly understood. Co-transcriptional splicing requires assembly of a functional spliceosome on nascent pre-mRNA, but whether and how this influences Pol II transcription remains unclear. Here we show that inhibition of pre-mRNA branch site recognition by the spliceosome component U2 snRNP leads to a widespread and strong decrease in new RNA synthesis in human cells. more...

(Submitter supplied) Calcium Homeostasis Endoplasmic Reticulum Protein (CHERP) is co-localized with inositol 1,4,5-trisphosphate receptor (IP3R) in the endoplasmic reticulum or peri-nuclear part, and has been considered to have a role in intracellular calcium signaling. Recently, it has recognized that CHERP structurally carries nuclear localization signal and arginine/serine-dipeptide repeats like domain, and interacts with spliceosome. more...

(Submitter supplied) Combinatorially, intron excision within a given nascent transcript could proceed down any of thousands of paths, each of which would expose different dynamic landscapes of cis-elements and contribute to alternative splicing. In this study, we found that post-transcriptional multi-intron splicing order in human cells is largely predetermined, with most genes spliced in one or a few predominant orders. more...

(Submitter supplied) Using wild type HEK293T cells and our DBR1 CRISPR knockout cell line (C22), we investigated the effect of AQR knockdown on cellular lariat levels. Samples were taken after transfection with either one of two AQR-targeting siRNAs or a non-targeting control siRNA. After sequencing the samples, lariat mapping of the reads revealed that AQR knockdown increased the lariat recovery rate by ~50% relative to the level observed in the negative control samples.

(Submitter supplied) We used CRISPR in HEK293T cells to create two DBR1 knockout cell lines (C19 and C22). After high-throughput sequencing of total RNA extracted from these cells, we performed lariat read mapping using the method described in "Large-scale mapping of branchpoints in human pre-mRNA transcripts in vivo" (Taggart et al, 2012). We found lariats in the two DBR1- cell lines to be ~20-fold enriched relative to the levels observed in the HEK293T control samples.

(Submitter supplied) We constructed a DBR1 knockout cell line (C22) using CRISPR in HEK293T cells. Through mapping of lariat reads, lariat levels in the DBR1 - samples are shown to increase dramatically (~20x) relative to wild type cells. Over 60% of this increase in lariat levels is abrogated upon rescue of DBR1 - cells with a DBR1 expression vector

(Submitter supplied) RNA polymerase III (Pol III) activity in cancer is linked to the production of small noncoding (nc)RNAs that are otherwise silent in most tissues. snaR-A (small NF90-associated RNA isoform A) - a hominid-specific ncRNA shown to enhance cell proliferation, migration, and invasion - is a cancer-emergent Pol III product that remains largely uncharacterized despite promoting growth phenotypes. Here, we applied a combination of genomic and biochemical approaches to predict the biogenesis and subsequent protein interactions of snaR-A to better understand its role as a putative driver of cancer progression. more...
