P2RX7 Antibody – Rabbit Polyclonal

The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel and is responsible for ATP-dependent lysis of 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. Multiple alternatively spliced variants have been identified, most of which fit nonsense-mediated decay (NMD) criteria. [provided by RefSeq, Jul 2010]

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.
