  • Applications

    Blocking

  • Form

    Liquid
  • Additional notes

    This is the blocking peptide for ab109246

    - First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
    - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
    - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
    - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
    - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

  • Function

    Receptor for ATP that acts as a ligand-gated ion channel. Responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells.
  • Tissue specificity

    Widely expressed with highest levels in brain and immune tissues.
  • Sequence similarities

    Belongs to the P2X receptor family.
  • Post-translational
    modifications

    Phosphorylation results in its inactivation.
    ADP-ribosylation at Arg-125 is necessary and sufficient to activate P2RX7 and gate the channel.
    Palmitoylation of several cysteines in the C-terminal cytoplasmic tail is required for efficient localization to cell surface.
  • Cellular localization

    Cell membrane.
  • Information by UniProt
