Authors demonstrate that under supersaturating conditions, dfmr1 mutant mitochondria have significantly increased maximum electron transport system (ETS) capacity.
Stored oocytes lacking FMR1 usually generate embryos with severe neural defects, unlike stored wild-type oocytes, which suggests that translation of multiple large proteins by stored mRNAs is defective in fragile X syndrome and possibly other autism spectrum disorders.
This FMRP activity is mediated solely via a second conserved RNA-binding protein, LIN-28, known to boost insulin signaling in stem cells. Via LIN-28, FMRP controls progenitor cell behavior by post-transcriptionally repressing the level of insulin receptor (InR).
DTor and DFMRP immunoreactivities were partially colocalized in several cellular organelles in larval muscles
Synaptic release of neuropeptides and neurotrophins depends on presynaptic accumulation of dense-core vesicles (DCVs). At rest, DCVs are captured bidirectionally as they circulate through Drosophila motoneuron terminals by anterograde and retrograde transport. Here we show that activity stimulates further synaptic capture that is distinguished from basal capture by its selectivity for anterograde DCVs and its inhibition b
Fmr1 protein associates with ninaE mRNA and represses its translation.

Bioinformatic analysis of the protein networks implies potentially novel functions for beta-catenin, particularly in mRNA translation, and we confirm a direct interaction between beta-catenin and the fragile X mental retardation protein (FMRP).
Various CGG expansions of the FMR1 allele may lead to changes of RNA levels and ratios of distinct FMRP RNA isoforms, which could regulate the translation and/or cellular localization of FMRP, affect the expression of steroidogenic enzymes and hormonal receptors, or act in some other epigenetic process and therefore result in the ovarian dysfunction in infertility.

Combining genetic knockdown of GKAP and pharmacological inhibition of NMDAR, study implicates FMRP and HSF1 as downstream effectors, which along with GKAP demonstrably support invasiveness of PanNET and pancreatic ductal adenocarcinoma cancer cells.
We measured the rate of protein synthesis in fibroblasts derived from 32 individuals with Fragile X syndrome (FXS) and from 17 controls as well as in fibroblasts and primary neurons of 27 Fmr1 KO mice and 20 controls. Here, we show that levels of protein synthesis are increased in fibroblasts of individuals with FXS and Fmr1 KO mice
Results provide evidence that the developmental delay is the cumulative result of a methylated FMR1 full mutation on the active X-chromosome and the inactivation of the other homologue carrying de novo 439 kb deletion.
At the molecular level, Fragile X-associated tremor/ataxia syndrome is characterized by increased expression of FMR1 sense and antisense RNA containing expanded CGG or GGC repeats, respectively

The knockdown of FMRP induced miR-181a expression and contributed to endothelial cell proliferation and angiogenesis. Authors identified CaM as a downstream target of miR-181a in endothelial cells.
Study found no significant relationship between the longitudinal changes of the CGG repeat in the FMR1 promoter region and premature ovarian failure etiology which can be attributed to the genetic heterogeneity nature of the disease, the possible involvement of the other genomic variations with the ovarian function and the reproductive health.
Agenet domain of FMRP binds FUS.
Our male patient had a pattern of the FMR1 size mosaic with both premutation (129 CGG) and full mutation (over 200) fragments
AKT inhibition led to decreased FMRP levels, as expected due to the known FMR1/FMRP negative feedback loop. But rFSH and the mTOR inhibition increased them, indicating a decoupling of this FMR1/FMRP negative feedback loop in our model system

We found that the impaired homeostatic synaptic downscaling in Fmr1 KO neurons is caused by loss-of-function dephosphorylation of an epilepsy-associated ubiquitin E3 ligase, neural precursor cell expressed developmentally down-regulated gene 4-2, Nedd4-2. Such dephosphorylation of Nedd4-2 is surprisingly caused by abnormally stable tumor suppressor p53 and subsequently destabilized kinase Akt.

Interplay between FMRP and lncRNA TUG1 regulates axonal development through mediating SnoN-Ccd1 pathway
Study found delays in auditory brainstem nucleus development and imbalances in synaptic input, which potentially contribute to the hyperacusis found in adult Fmr1 KO mice. Findings show developmental effects at very young ages, implying that early developmental events initiate some of the auditory phenotypes in fragile X syndrome.

this study establishes that reducing STEP activity with TC-2153 in Fmr1 KO mice reduces AGS susceptibility, improves electrophysiologic and synaptic deficits, and normalizes select social and nonsocial anxiety-related behaviors.
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.
