The human SWI/SNF subunit Brm is a regulator of alternative splicing

Abstract

The SWI/SNF (mating-type switch/sucrose nonfermenting) complex involved in chromatin remodeling on promoters has also been detected on the coding region of genes. Here we show that SWI/SNF can function as a regulator of alternative splicing. We found that the catalytic subunit Brm favors inclusion of variant exons in the mRNA of several genes, including E-cadherin, BIM, cyclin D1 and CD44. Consistent with this, Brm associates with several components of the spliceosome and with Sam68, an ERK-activated enhancer of variant exon inclusion. Examination of the CD44 gene revealed that Brm induced accumulation of RNA polymerase II (RNAPII) with a modified CTD phosphorylation pattern on regions encoding variant exons. Altogether, our data suggest that on genes regulated by SWI/SNF, Brm contributes to the crosstalk between transcription and RNA processing by decreasing RNAPII elongation rate and facilitating recruitment of the splicing machinery to variant exons with suboptimal splice sites.

  • BRM knockdown decreases RNA Pol II accumulation on alternatively spliced exons as measured by RNA Pol II ChIP.

    “Indeed, BRM knockdown has been shown to decrease RNA Pol II accumulation on alternatively spliced exons as measured by RNA Pol II ChIP (Batsché et al, 2006).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
