Immunogen

KLH-conjugated linear peptide corresponding to 18 amino acids from the C-terminal region of human Synaptic functional regulator FMR1.

Application

Affinity Binding Assay: A representative lot of this antibody bound FMR1 peptide with a KD of 7.0 x 10-8 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected FMR1 (C-terminal) in human testis tissue sections.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected FMR1 (C-terminal) in HeLa, A431, HUVEC, and NIH 3T3 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Target description

Synaptic functional regulator FMR1 (UniProt: Q06787; also known as Fragile X mental retardation protein 1, FMRP, Protein FMR-1) is encoded by the FMR1 gene (Gene ID: 2332) in human. FMR-1 is a homodimeric multifunctional polyribosome-associated RNA-binding protein predominantly found in the brain. It can also form heterodimer with FXR1 in a methylation-dependent manner. It shuttles between nucleus and cytoplasm in a XPO1/CRM1-dependent manner and plays a central role in neuronal development and synaptic plasticity through the regulation of alternative mRNA splicing, mRNA stability, mRNA dendritic transport and postsynaptic local protein synthesis of a subset of mRNAs. FMR-1 plays a role in mRNA nuclear export and together with export factor NXF2, it is involved in the regulation of the NXF1 mRNA stability in neurons. It stabilizes the scaffolding postsynaptic density protein DLG4/PSD-95 and the myelin basic protein mRNAs in hippocampal neurons and glial cells, respectively and this stabilization is further increased in response to metabotropic glutamate receptor (mGluR) stimulation. In response to mGluR stimulation, FMR1-target mRNAs are rapidly derepressed, allowing for local translation at synapses. FMR-1 is shown to play a role in the modulation of the sodium-activated potassium channel KCNT1 gating activity and negatively regulate the voltage-dependent calcium channel current density in soma and presynaptic terminals of dorsal root ganglion (DRG) neurons. FMR-1 is phosphorylated on several serine residues and phosphorylation at serine 500 is required for phosphorylation of other nearby serine residues. Although phosphorylation has no effect on the binding of individual mRNA species, it may affect the association with polyribosome. Unphosphorylated FMR1 is reported to associate with actively translating polyribosome, whereas a fraction of phosphorylated FMR1 is associated with apparently stalled polyribosome. Mutations in FMR1 gene are linked to Fragile X syndrome that is characterized by moderate to severe mental retardation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
