    • 功能:
      Multifunctional polyribosome-associated RNA-binding protein that plays a central role in neuronal development and synaptic plasticity through the regulation of alternative mRNA splicing, mRNA stability, mRNA dendritic transport and postsynaptic local protein synthesis of a subset of mRNAs. Plays a role in the alternative splicing of its own mRNA. Plays a role in mRNA nuclear export. Together with export factor NXF2, is involved in the regulation of the NXF1 mRNA stability in neurons. Stabilizes the scaffolding postsynaptic density protein DLG4/PSD-95 and the myelin basic protein (MBP) mRNAs in hippocampal neurons and glial cells, respectively; this stabilization is further increased in response to metabotropic glutamate receptor (mGluR) stimulation. Plays a role in selective delivery of a subset of dendritic mRNAs to synaptic sites in response to mGluR activation in a kinesin-dependent manner. Plays a role as a repressor of mRNA translation during the transport of dendritic mRNAs to postsynaptic dendritic spines. Component of the CYFIP1-EIF4E-FMR1 complex which blocks cap-dependent mRNA translation initiation. Represses mRNA translation by stalling ribosomal translocation during elongation. Reports are contradictory with regards to its ability to mediate translation inhibition of MBP mRNA in oligodendrocytes. Also involved in the recruitment of the RNA helicase MOV10 to a subset of mRNAs and hence regulates microRNA (miRNA)-mediated translational repression by AGO2. Facilitates the assembly of miRNAs on specific target mRNAs. Plays also a role as an activator of mRNA translation of a subset of dendritic mRNAs at synapses. In response to mGluR stimulation, FMR1-target mRNAs are rapidly derepressed, allowing for local translation at synapses. Binds to a large subset of dendritic mRNAs that encode a myriad of proteins involved in pre- and postsynaptic functions. Binds to 5'-ACUbinds to RNA homomer; preferentially on poly(G) and to a lesser extent on poly(U), but not on poly(A) or poly(C). May bind to RNA in Cajal bodies.; binds to RNA homomer; preferentially on poly(G) and to a lesser extent on poly(U), but not on poly(A) or poly(C). May bind to RNA in Cajal bodies.; (Microbial infection) Acts as a positive regulator of influenza A virus (IAV) replication. Required for the assembly and nuclear export of the viral ribonucleoprotein (vRNP) components.

      12. The naturally occurring Fragile XFMR1 5' region undergoes inactivation post implantation in a Dicer/Ago-dependent targeted process which involves local SUV39H-mediated tri-methylation of histone H3K9. Fragile X syndrome may come about through inadvertent siRNA-mediated heterochromatinization. PMID: 28621425
      13. The learning disability fragile X syndrome results from the presence of >200 CGG/CCG repeats in exon 1 of the X-linked gene FMR1. Such alleles arise by expansion from maternally transmitted FMR1 premutation alleles, alleles having 55 to 200 repeats. Expansion risk is directly related to maternal repeat number.

      22. The characterization of the expression levels of the different FMR1 isoforms is fundamental for understanding the regulation of the FMR1 gene as imbalance in their expression could lead to an altered functional diversity with neurotoxic consequences. Their characterization will also help to elucidating the mechanism(s) by which "toxic gain of function" of the FMR1 mRNA may play a role in Fragile X-associated tremorAtaxia. PMID: 28888471

      24. Authors found that 5hmC enrichment at the FMR1 locus in FXS cells is specific to neurons by utilizing a nuclei sorting technique to separate neuronal and glial DNA fractions from post-mortem brain tissues.

      28. There is no robust evidence in this large study that variation within the normal range of FMR1 repeat alleles influences timing of menopause in the general population, which contradicts findings from some earlier, mainly smaller studies. The FMR1 CGG repeat polymorphism in the normal range is unlikely to contribute to genetic susceptibility to early menopause. PMID: 27614355

PMID: 26741412
      32. In the PM group, the lack of any significant association between FMR1 mRNA levels and phenotypic measures found in this study suggests that either FMR1 expression is not well conserved between tissues, or that FMR1 intron 1 methylation is linked to neuroanatomical and cognitive phenotype in PM females via a different mechanism. PMID: 27959330

      40. Fmr1 knockout (KO) mice show widespread changes in histone marks as well as transcriptional misregulation resulting in increased expression of many critical synaptic genes. Data suggest that one chromatin target of FMRP, the reader protein Brd4, appears to be significantly involved in this transcriptional disruption. PMID: 28823556
      41. We found 230 different alleles of which the most frequent are 10A9A9 (38.4%), 9A9A9 (15.1%), and 10A9 (10.5%). Furthermore, alleles with 0 AGG interruptions or with a pure (uninterrupted) CGG repeat run larger than 34 (presumably more unstable), were more frequent among premutation alleles compared to normal alleles. PMID: 27333191
      42. The study establishes a functional/physical partnership between FMRP and TDP-43 that mechanistically links several neurodevelopmental disorders and neurodegenerative diseases. PMID: 27518042

      47. Expression of FMRpolyG is pathogenic, while the sole expression of CGG RNA is not. FMRpolyG interacts with the nuclear lamina protein LAP2beta and disorganizes the nuclear lamina architecture in neurons differentiated from FXTAS iPS cells. Finally, expression of LAP2beta rescues neuronal death induced by FMRpolyG. PMID: 28065649
