CC -!- FUNCTION: mRNA-binding protein that acts as a regulator of mRNAs CC translation and/or stability, and which is required for adult CC hippocampal neurogenesis (PubMed:21658585). Specifically binds to AU- CC rich elements (AREs) in the 3'-UTR of target mRNAs (PubMed:21658585). CC Promotes formation of some phase-separated membraneless compartment by CC undergoing liquid-liquid phase separation upon binding to AREs- CC containing mRNAs: mRNAs storage into membraneless compartments CC regulates their translation and/or stability (By similarity). Acts as a CC regulator of adult hippocampal neurogenesis by regulating translation CC and/or stability of NOG mRNA, thereby preventing NOG protein expression CC in the dentate gyrus (PubMed:21658585). {ECO:0000250|UniProtKB:Q61584, CC ECO:0000269|PubMed:21658585}. CC -!- SUBUNIT: Interacts with FMR1 (By similarity). Interacts with FXR1 (By CC similarity). Interacts with TDRD3 (By similarity). Interacts with HABP4 CC (By similarity). Interacts with CYFIP2 but not with CYFIP1 CC (PubMed:11438699). {ECO:0000250|UniProtKB:P51116, CC ECO:0000269|PubMed:11438699}. CC -!- SUBCELLULAR LOCATION: Cytoplasm, Cytoplasmic ribonucleoprotein granule CC {ECO:0000250|UniProtKB:Q61584}. Cytoplasm CC {ECO:0000269|PubMed:11875043}. Postsynapse CC {ECO:0000269|PubMed:27770568}. Note=Specifically localizes to CC cytoplasmic ribonucleoprotein membraneless compartments (By CC similarity). Localization to the post-synaptic region is dependent on CC FMR1 (PubMed:27770568). {ECO:0000250|UniProtKB:Q61584, CC ECO:0000269|PubMed:27770568}. CC -!- TISSUE SPECIFICITY: Highly expressed in brain and testis CC (PubMed:11875043). In brain, expressed in the subventricular zone of CC the lateral ventricles and in most of the granule neurons of the CC dentate gyrus of the hippocampus (PubMed:21658585). CC {ECO:0000269|PubMed:11875043, ECO:0000269|PubMed:21658585}. CC -!- DOMAIN: The tandem Agenet-like domains preferentially recognize CC trimethylated histone peptides. {ECO:0000250|UniProtKB:P51116}. CC -!- DOMAIN: Disordered region at the C-terminus undergoes liquid-liquid CC phase separation (LLPS) for the formation of a membraneless compartment CC that stores mRNAs. {ECO:0000250|UniProtKB:Q61584}. CC -!- DISRUPTION PHENOTYPE: No visible phenotype; mice are viable and fertile CC and do not exhibit any overt phenotype (PubMed:11875043). Mice however CC show behavioral abnormalities, characterized by hyperactivity CC (PubMed:11875043). Increased proliferation of radial glia-like neural CC stem/progenitor cells in the adult dentate gyrus caused by increased CC Nog (Noggin) expression and subsequently reduced BMP signaling CC (PubMed:21658585). Misregulation of a number of transcripts involved in CC memory or cognitions is observed in the brain of mutant mice CC (PubMed:18930145). Mice lacking both Fxr2 and Fmr1 display exaggerated CC learning deficits, characterized by prepulse inhibition of acoustic CC startle response and contextual fear conditioning compared with single CC mutant (Fxr2 or Fmr1) mice (PubMed:16675531). CC {ECO:0000269|PubMed:11875043, ECO:0000269|PubMed:16675531, CC ECO:0000269|PubMed:18930145, ECO:0000269|PubMed:21658585}. CC -!- SIMILARITY: Belongs to the FMR1 family. {ECO:0000305}.
