The multifunctional RNA-binding protein hnRNP A1 is required for processing of miR-18a
Abstract
hnRNP A1 is an RNA-binding protein involved in various aspects of RNA processing. Use of an in vivo cross-linking and immunoprecipitation protocol to find hnRNP A1 RNA targets resulted in the identification of a microRNA (miRNA) precursor, pre-miR-18a. This microRNA is expressed as part of a cluster of intronic RNAs, including miR-17, miR-18a, miR-19a, miR-20a, miR-19b-1 and miR-92, and potentially acts as an oncogene. Here we show that hnRNP A1 binds specifically to the primary RNA sequence pri-miR-18a before Drosha processing. HeLa cells depleted of hnRNP A1 have reduced in vitro processing activity with pri-miR-18a and also show reduced abundances of endogenous pre-miR-18a. Furthermore, we show that hnRNP A1 is required for miR-18a-mediated repression of a target reporter in vivo. These results underscore a previously uncharacterized role for general RNA-binding proteins as auxiliary factors that facilitate the processing of specific miRNAs.

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.
