The Cytolytic P 2Z Receptor for Extracellular ATP Identified as a P 2X Receptor (P2X 7 )

Abstract

The P 2Z receptor is responsible for adenosine triphosphate (ATP)-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Other ATP-gated channels, the P 2X receptors, are permeable only to small cations. Here, an ATP receptor, the P2X 7 receptor, was cloned from rat brain and exhibited both these properties. This protein is homologous to other P 2X receptors but has a unique carboxyl-terminal domain that was required for the lytic actions of ATP. Thus, the P2X 7 (or P 2Z ) receptor is a bifunctional molecule that could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
