Gene Information

human ... FXR2(9513)

General description

Monoclonal Anti-FXR2 (mouse IgG1 isotype) is derived from the hybridoma A42 produced by the fusion of mouse myeloma cells (NS1 cells) and splenocytes from BALB/c mice immunized with human Fragile X mental retardation syndrome-related protein 2 (FXR2) recombinant protein. FXR2 gene is located on human chromosome 17 and its protein is localized mainly in the cytoplasm. FXR2 is expressed along with other proteins in the cytoplasm of neurons. It is characterized with two KH domains and one RGG box that together with fragile X mental retardation 1 (FMR1) bind to RNA. FXR2 is highly expressed in brain and testis.


Monoclonal Anti-FXR2 recognizes human, monkey, bovine, canine, rat, hamster, and mouse, FXR2, ~74 kDa, and does not crossreact with FMR or FXR1.


human FXR2 recombinant protein.


Anti-FXR2 antibody, Mouse monoclonal may be used in:
  • immunoblotting
  • immunoprecipitation
  • immunocytochemistry
  • immunohistochemistry
  • co-immunoprecipitation
  • immunofluorescence
  • sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)

Biochem/physiol Actions

Fragile X mental retardation syndrome-related protein 2 (FXR2) knockout mice are hyperactive in the open-field test, impaired on the rotarod test, have reduced levels of prepulse inhibition, display less contextual conditioned fear, are impaired at locating the hidden platform in the Morris water task, and less sensitive to heat stimulus.
Fragile X mental retardation syndrome-related protein 2 (FXR2) is capable of forming heteromers with the others and can also form homomers. It has an independent function in tissues during embryonic development and adult life.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2–8 °C for up to one month. For prolonged storage, freeze in working aliquots. Repeated freezing and thawing, or storage in frost-free freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
