The regulation of mRNA stability in mammalian cells: 2.0

Open access
Wu, Xiangyue, Brewer, Gary·2012·Gene

Abstract

Messenger RNA decay is an essential step in gene expression to set mRNA abundance in the cytoplasm. The binding of proteins and/or noncoding RNAs to specific recognition sequences or secondary structures within mRNAs dictates mRNA decay rates by recruiting specific enzyme complexes that perform the destruction processes. Often, the cell coordinates the degradation or stabilization of functional subsets of mRNAs encoding proteins collectively required for a biological process. As well, extrinsic or intrinsic stimuli activate signal transduction pathways that modify the mRNA decay machinery with consequent effects on decay rates and mRNA abundance. This review is an update to our 2001 Gene review on mRNA stability in mammalian cells, and we survey the enormous progress made over the past decade.

  • Out of the roughly 20 currently known AUBPs, the majority are expressed in neurons and promote mRNA decay, including AUF1, TTP, and KSRP.

    “Out of the roughly 20 currently known AUBPs, the majority are expressed in neurons and promote mRNA decay including, for example, AUF1, TTP, and KSRP (Table 1; Wu and Brewer 2012).”

    From Emerging complexity of the HuD/ELAVl4 gene; implications for neuronal development, function, and dysfunction (2013) · cites this paper as Wu and Brewer 2012

    Section 4.1 says there are about 20 known AUBPs, that most recruit mRNA-degradation machinery, and that AUF1, TTP, and KSRP promote degradation. It does not establish that a majority of AUBPs are expressed in neurons. (LLM, conf=0.90)

  • Destabilizing RBPs may promote deadenylation by blocking poly(A) binding protein (PABP) binding and/or recruiting decapping, deadenylation, and exosome components.

    “Once bound to a target mRNA, destabilizing RBPs may promote deadenylation through a variety of manners such as blocking poly(A) binding protein (PABP) binding and/or recruitment of decapping, deadenylation, and exosome components (Wu and Brewer 2012).”

    From Emerging complexity of the HuD/ELAVl4 gene; implications for neuronal development, function, and dysfunction (2013) · cites this paper as Wu and Brewer 2012

    Section 4.1 says AUF1 may prevent PABP from binding poly(A), allowing deadenylases access, and that KSRP, TTP, and BRF1 interact with deadenylation, decapping, and exosome factors. It describes those recruited factors as promoting mRNA degradation overall, however, and places exosome-mediated degradation after deadenylation; it does not say that recruiting decapping or exosome components promotes deadenylation itself. (LLM, conf=0.83)

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.
