Our Abpromise guarantee covers the use of ab5839 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications


  • Purity
    > 95 % SDS-PAGE.

  • Form
  • Additional notes

    This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and ITP Receptor Type I, catalog ab5804. Using a solution with equal weights per unit volume of peptide and corresponding antibody will yield a solution with a large molar excess of peptide that is able to competitively bind the antibody.

  • Function
    Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate.
  • Tissue specificity
    Widely expressed.
  • Involvement in disease
    Defects in ITPR1 are the cause of spinocerebellar ataxia type 15 (SCA15) (SCA15) [MIM:606658]. Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA15 is an autosomal dominant cerebellar ataxia (ADCA). It is very slow progressing form with a wide range of onset, ranging from childhood to adult. Most patients remain ambulatory.
  • Sequence similarities
    Belongs to the InsP3 receptor family.
    Contains 5 MIR domains.
  • Domain
    The receptor contains a calcium channel in its C-terminal extremity. Its large N-terminal cytoplasmic region has the ligand-binding site in the N-terminus and modulatory sites in the middle portion immediately upstream of the channel region.
  • Post-translational
    Phosphorylated by cAMP kinase. Phosphorylation prevents the ligand-induced opening of the calcium channels.
    Phosphorylated on tyrosine residues.
  • Cellular localization
    Endoplasmic reticulum membrane.
  • Information by UniProt

I would recommend to follow the protocol we have on our website. The use of 2 times the concentration of peptide (compared to the antibody concentration) represents a large and sufficient excess to block the antibody. I hope this is helpful. Do not hes...
