P2X7 Antibody – Rat Monoclonal

P2X7: a receptor for ATP that acts as a ligand-gated ion channel. Responsible for ATP-dependent lysis by macrophages through the formation of membrane pores permeable to large molecules. Activation of this nuclear receptor by ATP in the cytoplasm may be a mechanism by which cellular activity can be coupled to changes in gene expression. Alternatively spliced variants encoding different isoforms have been identified. Could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells. Phosphorylation results in its inactivation.
