Abstract

The embryonic lethal abnormal visual system (ELAV) is a gene-specific regulator of alternative pre-mRNA processing in neurons of Drosophila. Here we define a functional in vivo binding site for ELAV in neurons through the development of a reporter gene system in transgenic animals in combination with in vitro binding assays. ELAV binds to erect wing (ewg) RNA 3′ of a polyadenylation site in the terminal intron 6. At this polyadenylation site, ELAV inhibits 3′-end processing in vitro in a dose-dependent and sequence-specific manner, and ELAV binding is necessary in vivo to promote splicing of ewg intron 6. Further, the AAUAAA poly(A) complex recognition sequence, together with ELAV, is required to regulate neural 3′ splice site choice in vivo. In addition, the use of segmentally labeled RNA substrates in UV cross-linking assays suggest that ELAV does not inhibit or redirect binding of cleavage factor dCstF64 at the regulated polyadenylation site on ewg RNA. These data indicate that binding of 3′-end processing factors, together with ELAV, can regulate alternative splicing.

  • Both the Drosophila ELAV and the mammalian Hu proteins control alternative polyadenylation specifically in neurons.

    “In addition to alternative splicing, both the Drosophila ELAV and the mammalian Hu proteins were demonstrated to control alternative polyadenylation specifically in neurons (Soller and White 2003).”

    From Emerging complexity of the HuD/ELAVl4 gene; implications for neuronal development, function, and dysfunction (2013) · cites this paper as Soller and White 2003

    The Discussion reports that Drosophila ELAV inhibits 3′-end formation at an intronic polyadenylation site, promoting neuronal splicing of ewg. The paper does not demonstrate the same control by mammalian Hu proteins; its introductory passage instead describes their previously assigned functions as cytoplasmic 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.
