Abstract

In Drosophila, the PIWI proteins, Aubergine (Aub), AGO3, and Piwi are expressed in germlines and function in silencing transposons by associating with PIWI-interacting RNAs (piRNAs). Recent studies show that PIWI proteins contain symmetric dimethyl-arginines (sDMAs) and that dPRMT5/Capsuleen/DART5 is the modifying enzyme. Here, we show that Tudor (Tud), one of Tud domain-containing proteins, associates with Aub and AGO3, specifically through their sDMA modifications and that these three proteins form heteromeric complexes. piRNA precursor-like molecules are detected in these complexes. The expression levels of Aub and AGO3, along with their degree of sDMA modification, were not changed by tud mutations. However, the population of transposon-derived piRNAs associated with Aub and AGO3 was altered by tud mutations, whereas the total amounts of small RNAs on Aub and AGO3 was increased. Loss of dprmt5 did not change the stability of Aub, but impaired its association with Tud and lowered piRNA association with Aub. Thus, in germline cells, piRNAs are quality-controlled by dPRMT5 that modifies PIWI proteins, in tight association with Tud.

  • csul interacts with histones, spliceosomal proteins and other small ribonucleoproteins and can affect protein-RNA affinity and intracellular localization of certain mRNAs.

    “The gene csul interacts with histones, splicesosomal proteins and other small ribonucleoproteins and can affect protein–RNA affinity and intracellular localization of certain mRNAs (70–72).”

    From Functional genomic screen and network analysis reveal novel modifiers of tauopathy dissociated from tau phosphorylation (2011) · cites this paper as [72]

    The Introduction identifies Csul as dPRMT5 and discusses methylation of spliceosomal Sm proteins and snRNP assembly. The section ‘sDMA modification of Aub affects PIWI-piRNA loading’ reports effects on Aub’s association with piRNAs and Aub’s localization in nurse cells. Our copy does not establish Csul interactions with histones or other small ribonucleoproteins, or an effect on the intracellular localization of mRNAs; the localization result concerns a protein.

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.
