Abstract

Heterogeneous nuclear ribonucleoproteins (hnRNPs) have been traditionally seen as proteins packaging RNA nonspecifically into ribonucleoprotein particles (RNPs), but evidence suggests specific cellular functions on discrete target pre-mRNAs. Here we report genome-wide analysis of alternative splicing patterns regulated by four Drosophila homologs of the mammalian hnRNP A/B family (hrp36, hrp38, hrp40, and hrp48). Analysis of the global RNA-binding distributions of each protein revealed both small and extensively bound regions on target transcripts. A significant subset of RNAs were bound and regulated by more than one hnRNP protein, revealing a combinatorial network of interactions. In vitro RNA-binding site selection experiments (SELEX) identified distinct binding motif specificities for each protein, which were overrepresented in their respective regulated and bound transcripts. These results indicate that individual heterogeneous ribonucleoproteins have specific affinities for overlapping, but distinct, populations of target pre-mRNAs controlling their patterns of RNA processing.

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.
