General description

FMR1 is a RNA binding protein expressed mainly in brain, neurons, placenta, testes and lymphocytes. Defect in FMR1 can lead to Fragile X Mental Retardation Syndrome due to lack of expression of FMR1 or expression of a mutant protein that cannot bind RNA. Anti-FMR1 (C-terminal) antibody can be used in immunofluorescence staining. Rabbit anti-FMR1 (C-terminal) antibody reacts specifically with FMR1.
The FMR1 protein (fragile X mental retardation 1 protein) can bind to RNA. It contains two heterogeneous nuclear ribonucleoprotein K homology (KH) domains and one RGG box. Two proteins named FXR1 and FXR2 interact with FMR1. The protein is highly expressed in brain and testis.


synthetic peptide corresponding to amino acids 606-623 of human FMR1, conjugated to KLH. The corresponding sequence is highly conserved (1 amino acid substitution) in rat and mouse.


Anti-FMR1 (C-terminal) antibody produced in rabbit has been used in: western blotting, immunoprecipitation, immunofluorescence, immunoblotting .
