Fragile X mental retardation protein control of neuronal mRNA metabolism: Insights into mRNA stability

De Rubeis, Silvia, Bagni, Claudia·2010·Molecular and Cellular Neuroscience

Abstract

The fragile X mental retardation protein (FMRP) is an RNA binding protein that has an essential role in neurons. From the soma to the synapse, FMRP is associated with a specific subset of messenger RNAs and controls their posttranscriptional fates, i.e., dendritic localization and local translation. Because FMRP target mRNAs encode important neuronal proteins, the deregulation of their expression in the absence of FMRP leads to a strong impairment of synaptic function. Here, we review emerging evidence indicating a critical role for FMRP in the control of mRNA stability. To date, two mRNAs have been identified as being regulated in this manner: PSD-95 mRNA, encoding a scaffolding protein, and Nxf1 mRNA, encoding a general export factor. Moreover, expression studies suggest that the turnover of other neuronal mRNAs, including those encoding for the GABA(A) receptors subunits, could be affected by the loss of FMRP. According to the specific target and/or cellular context, FMRP could influence mRNA stability in the brain.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • FMRP is an RNA-binding protein that regulates target RNAs post-transcriptionally and binds about 4% of brain mRNA.

    “FMRP, translated from the Fragile X mental retardation-1 (FMR1) gene, is an RNA-binding protein involved in post-transcriptional regulation of target RNAs [157] and binds approximately 4% of the mRNA expressed in the brain [158].”

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.
