  • 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

    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.

  • C57BL6 mouse splenocytes were incubated with Rat IgG2b, kappa monoclonal [RTK4530] (ab18541) (left) or anti-P2X7 [F11] antibody (ab233698) (right) at 10ug/ml for 30 min at 4+°C. The secondary antibody Goat Anti-Rat IgG H&L (Alexa Fluor® 488) (ab150157) was used at 1/2000 dilution for 30 min at 4+°C. The cells were simultaneously stained with anti-CD3ε PerCP (10ug/ml) (ab190299).

    Acquisition of >30,000 total events were collected. Gating strategy - live lymphocytes

  • IHC image of ab195356 staining in 10% formaldehyde fixed frozen tissue section of normal mouse large intestine.

    Non-specific protein-protein interactions were blocked using TBS containing 0.025% (v/v) Triton X-100, 0.3M (w/v) glycine and 3% (w/v) BSA for 1h at room temperature. The section was then incubated with ab195356 (1μg/ml) in TBS containing 0.025% (v/v) Triton X-100 and 3% (w/v) BSA overnight at +4°C. The section was then incubated with ab150167 (Goat polyclonal Secondary Antibody to Rat IgG - H&L (Alexa Fluor® 647)) and DAPI for 1 hour at room temperature.

    The DAPI only control (no antibody) inset shows no autofluorescence, demonstrating that any Alexa Fluor® 647 signal is derived directly from bound ab195356. 

    For other IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antibody concentrations and incubation times.
