Abstract

Expression of many proto-oncogenes, cytokines and lymphokines is regulated by targeting their messenger RNAs for rapid degradation. Essential signals for this control are AU-rich elements (AREs) in the 3' untranslated region (UTR) of these messages. The ARE is loosely defined as the five-nucleotide sequence AUUUA embedded in a uracil-rich region. A transacting factor, presumably a protein, binds the ARE and initiates recognition by the destabilization machinery. Numerous candidate ARE-binding proteins have been proposed. We show that a 32 kDa protein in HeLa nuclear extracts characterized previously has RNA-binding specificity that correlates with the activity of an ARE in directing mRNA decay. Purification and subsequent analyses demonstrate that this 32 kDa protein is identical to a recently identified member of the Elav-like gene family (ELG) called HuR. The in vitro binding selectivity of HuR is indicative of an ARE sequence's ability to destabilize a mRNA in vivo, suggesting a critical role for HuR in the regulation of mRNA degradation.

  • The analysis identified known regulators of mRNA stability, including RBM4 and ELAVL1, and correctly predicted the direction of their effect (destabilizing for RBM4 and stabilizing for ELAVL1).

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.
