General Comment Tdrd3 is a novel stress granule-associated protein interacting with the Fragile-X syndrome protein FMRP. Linder B 2008 et al. Tudor domains are widespread among proteins involved in RNA metabolism, but only in a few cases their cellular function has been analyzed in detail. Here, we report on the characterization of the ubiquitously expressed Tudor domain containing protein Tdrd3. Apart from its Tudor domain, we show that Tdrd3 possesses an oligosaccharide/nucleotide binding fold (OB-fold) and an ubiquitin associated domain capable of binding tetra-ubiquitin. A set of biochemical experiments revealed an interaction of Tdrd3 with FMRP, the product of the gene affected in Fragile X syndrome, and its autosomal homologs FXR1 and FXR2. FMRP has been implicated in the translational regulation of target mRNAs and shown to be a component of stress granules (SG). We demonstrate that overexpression of Tdrd3 in cells induces the formation of SGs and as a result leads to its co-localization with endogenous FMRP in these structures. Interestingly, the disease-associated FMRP missense mutation I304N identified in a Fragile X patient severely impairs the interaction with Tdrd3 in biochemical experiments. We propose a contribution of Tdrd3 to FMRP-mediated translational repression and suggest that the loss of the FMRP-Tdrd3 interaction caused by the I304N mutation might contribute to the pathogenesis of Fragile X syndrome. /////////////////////////

Comment: Meta-analyses identify 13 loci associated with age at menopause and highlight DNA repair and immune pathways. Stolk L et al. To newly identify loci for age at natural menopause, we carried out a meta-analysis of 22 genome-wide association studies (GWAS) in 38,968 women of European descent, with replication in up to 14,435 women. In addition to four known loci, we identified 13 loci newly associated with age at natural menopause (at P < 5 ?10(-8)). Candidate genes located at these newly associated loci include genes implicated in DNA repair (EXO1, HELQ, UIMC1, FAM175A, FANCI, TLK1, POLG and PRIM1) and immune function (IL11, NLRP11 and PRRC2A (also known as BAT2)). Gene-set enrichment pathway analyses using the full GWAS data set identified exoDNase, NF-?B signaling and mitochondrial dysfunction as biological processes related to timing of menopause.
