      Background InformationFragile X-associated Tremor/Ataxia syndrome (FXTAS) is a neurodegenerative disorder caused by an elevated CGG-repeat expansions (55-200) in the 5′ UTR of the fragile-X mental retardation 1 gene FMR1 (also known as FRAXA, POF1; Gene ID 2332) on the X-chromosome. The CGG repeat expansion in FXTAS triggers repeat-associated non-ATG-initiated translation (RAN or RANT), also known as repeat-associated non-AUG-initiated translation, within the 5’UTR of FMR1 mRNA, resulting in the production of fusion proteins (FMR1polyG) that contain N-terminal polyglycine fused to either C-terminal FMR1 in-frame sequence or one of two FMR1 frame-shift sequences. Immunohistochemical analysis of FXTAS brain tissues reveals FMR1polyG-positive aggregates that closely resemble neuronal intranuclear inclusions seen in polyglutamine diseases and other protein-mediated neurodegenerative disorders. Much larger expansions of the same repeat cause fragile X syndrome (FRAX), the most common inherited form of mental retardation, by silencing FMR1 transcription.

      Applications
      ApplicationAnti-FMR1polyG Antibody, clone 9FM-1B7 is an antibody against FMR1polyG for use in Western Blotting, Immunohistochemistry.
      Key Applications
      • Western Blotting
      • Immunohistochemistry
      Application NotesImmunohistochemistry Analysis: A representative lot detected FMR1polyG immunoreactivity in paraffin-embedded brain tissue sections from an Fragile X-associated Tremor/Ataxia syndrome (FXTAS) patient, but not in brain tissues from non-FXTAS individuals (Buijsen, R.A., et al. (2014). Acta Neuropathol. Commun. 2:162).
      Western Blotting Analysis: A representative lot detected an exogenously expressed FMR1polyG EGFP fusion construct corresponding to 5′UTR of FMR1 with 50 CGG repeats (Buijsen, R.A., et al. (2014). Acta Neuropathol. Commun. 2:162).
      Biological Information

      SpecificityThis monoclonal antibody does not detect the Fragile X mental retardation protein 1 sequences reported by UniProt (Q06787-1 through Q06787-9). It detects one of the two possible types of FMR1 frame-shift sequences with N-terminal polyG fusion found in Fragile X-associated Tremor/Ataxia syndrome (FXTAS) patients due to CGG repeats expansion (55-200 repeats) in the 5’UTR of the FMR1 gene. Due to the extended aggregation of the pathological forms of FMR1polyG, the detection of FMR1polyG in patient samples by Western blotting is not recommended.
