Fruit Fly (Drosophila melanogaster) Fragile X Mental Retardation 1 (FMR1) interaction partners

  1. Fmr1 protein associates with ninaE mRNA and represses its translation.

  2. Our data strongly support a gain-of-function pathogenic mechanism of PQBP1 (show PQBP1 Proteins) c.459_462delAGAG and c.463_464dupAG mutations, and suggest that therapeutic strategies to restore FMRP function may be beneficial for those patients

  3. dFMRP cooperates with Piwi in maintaining genome integrity by silencing heterochromatic genes and suppressing transposon expression.

  4. results show Fragile X Mental Retardation Protein (FMRP) shapes neuron class-specific calcium signaling in excitatory vs. inhibitory neurons in developing learning/memory circuitry, and that FMRP mediates activity-dependent regulation of calcium signaling specifically during the early-use critical period.

  5. results support a model whereby dFMRP can modulate the neurotoxicity caused by TDP-43 (show TARDBP Proteins) overexpression

  6. demonstrate that Zfrp8 genetically interacts with Fmr1 and tral (show LSM14A Proteins) in an antagonistic manner. Zfrp8 and FMRP both control heterochromatin packaging, also in opposite ways

  7. dFmr1 protein is essential for proper cardiac function and establish the fly as a new model for studying the role(s) of FraX proteins in the heart.

  8. These results show that dfmr1 acts in a neuron type-specific activity-dependent manner for sculpting dendritic arbors during early-use, critical period development of learning and memory circuitry in the Drosophila brain.

  9. upon the stimulation of replication stress, dFMR1 is associated with chromatin in a domain-specific manner, which is essential for its ability to induce the phosphorylation of H2Av (show H2AFV Proteins).

  10. FMRP inhibits translation by binding directly to the L5 protein on the 80S ribosome.

Human Fragile X Mental Retardation 1 (FMR1) interaction partners

  1. 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 (show BRD4 Proteins), appears to be significantly involved in this transcriptional disruption.

  2. The study establishes a functional/physical partnership between FMRP and TDP-43 (show TARDBP Proteins) that mechanistically links several neurodevelopmental disorders and neurodegenerative diseases.

  3. High CGG trinucleotide repeat expansion in FMR1 gene is associated with fragile X syndrome.

  4. showing the potential of being applicable to other psychiatric disorders to identify endophenotype-specific responses relevant to neurobiology.-Napoli, E., Song, G., Schneider, A., Hagerman, R., Eldeeb, M. A. A. A., Azarang, A., Tassone, F., Giulivi, C. Warburg effect linked to cognitive-executive deficits in FMR1 premutation

  5. Data show that EZH2 (show EZH2 Proteins) plays a critical role in the FMR1 gene silencing process and that its inhibition can prolong expression of the FMR1 gene even in the presence of its transcript.

  6. Intragenic FMR1 variants, although much less frequent than CGG expansions, are a significant mutational mechanism leading to FXS.

  7. FMR1 triple CGG repeats in the normal range may be associated with primary ovarian insufficiency in China

  8. Expression of FMRpolyG is pathogenic, while the sole expression of CGG RNA is not. FMRpolyG interacts with the nuclear lamina protein LAP2beta (show TMPO Proteins) and disorganizes the nuclear lamina architecture in neurons differentiated from FXTAS iPS (show SLC27A4 Proteins) cells. Finally, expression of LAP2beta (show TMPO Proteins) rescues neuronal death induced by FMRpolyG.

  9. FMR1 CGG trinucleotide repeats were low in Caucasian women with diminished ovarian reserve.

  10. For routine screening of patients/carriers with full/pre-mutations of the FMR1 gene in the population.

Zebrafish Fragile X Mental Retardation 1 (FMR1) interaction partners

  1. We identified thousands of clustered RNA editing sites in the zebrafish transcriptome and showed that Fmrp biochemically interacts with the Adar2a protein. The expression levels of the adar (show ADAR Proteins) genes and Adar2 (show ADARB1 Proteins) protein increased in fmr1-/- zebrafish

  2. Loss-of-function fmr1 mutants carrying an anti-fmr1 miRNA transgene show abnormal neuronal morphology and connectivity similar to that seen in human fragile X syndrome.

Mouse (Murine) Fragile X Mental Retardation 1 (FMR1) interaction partners

  1. Fmr1-KO mice show significantly less daily movement during the dark cycle and more bouts of activity during the light cycle compared with wild types.

  2. these findings support the notion of FMRP differential neuronal regulation and strongly implicate the contribution of fundamental sensory and motor processing at subcortical levels to fragile X syndrome pathology

  3. In Fmr1 KO neurons, Mdm2 (show MDM2 Proteins) is hyperphosphorylated, nuclear localized basally, and unaffected by MEF2 (show MEF2C Proteins) activation, which our data suggest due to an enhanced interaction with Eukaryotic Elongation Factor (show TSFM Proteins) 1alpha (EF1alpha), whose protein levels are elevated in Fmr1 KO. Expression of a dephosphomimetic of Mdm2 (show MDM2 Proteins) rescues PSD-95 (show DLG4 Proteins) ubiquitination, degradation and synapse elimination in Fmr1 KO neurons.

  4. We show here that in mouse models PFC (show CFP Proteins) dysfunction in Fragile X Syndrome (FX) can be attributed to the continued absence of FMRP from the PFC (show CFP Proteins), independent of FMRP status during development.

  5. Loss of the Fragile X mental retardation protein (show NUFIP2 Proteins) leads to excessive excitatory compared with inhibitory inputs in neurons extracting information about sound levels. Functionally, this elevated excitation results in increased firing rates, and abnormal coding of frequency and binaural sound localization cues. Imbalanced early-stage sound level processing could partially explain the auditory processing deficits in FXS.

  6. The results of this study suggest dysregulated NMDARs in the pathophysiology of FXS leading to altered mGluR (show GRM8 Proteins)-mediated Long-Term Depression.

  7. FMRP mediates structural plasticity of olfactory bulb adult-born neurons to support olfactory learning through alphaCaMKII local translation.

  8. This study demonstrated that astrocyte-specific Fmr1 conditional knock-out and restoration mice, and provided compelling evidence that the selective loss of astroglial FMRP contributes to cortical synaptic deficits in FXS.

  9. FMRP is involved in pri-miRNA processing via enhancing DROSHA (show DROSHA Proteins) expression that may play an important role in fragile X syndrome.

  10. FMRP is likely to participate in retinal physiology, since its expression changes with light exposure. In addition, the expression pattern and regulation by light of FMRP seems well conserved since it was similar in both mouse and chick.

FMR1 Protein Profile

Protein Summary

The protein encoded by this gene binds RNA and is associated with polysomes. The encoded protein may be involved in mRNA trafficking from the nucleus to the cytoplasm. A trinucleotide repeat (CGG) in the 5' UTR is normally found at 6-53 copies, but an expansion to 55-230 repeats is the cause of fragile X syndrome. Expansion of the trinucleotide repeat may also cause one form of premature ovarian failure (POF1). Multiple alternatively spliced transcript variants that encode different protein isoforms and which are located in different cellular locations have been described for this gene.
