P2X7 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. In the absence of its natural ligand, ATP, functions as a scavenger receptor in the recognition and engulfment of apoptotic cells. Belongs to the P2X receptor family. Widely expressed with highest levels in brain and immune tissues. 8 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
