The protein encoded by this gene belongs to the family of P2X receptors, which are ATP-gated ion channels and mediate rapid and selective permeability to cations. This gene is predominantly expressed in skeletal muscle, and regulated by p53. The encoded protein is associated with VE-cadherin at the adherens junctions of human umbilical vein endothelial cells. Alternative splicing results in multiple transcript variants. A related pseudogene, which is also located on chromosome 22, has been identified. [provided by RefSeq, Apr 2009]

P2RX6 (Purinergic Receptor P2X, Ligand Gated Ion Channel, 6) is a Protein Coding gene. Among its related pathways are CREB Pathway and Calcium signaling pathway. GO annotations related to this gene include identical protein binding and channel activity. An important paralog of this gene is P2RX1.
UniProtKB/Swiss-Prot for P2RX6 Gene
Receptor for ATP that acts as a ligand-gated ion channel.
P2X receptors are members of the ligand-gated ion channel family that open in response to extracellular ATP. Each receptor is made up of a trimer of subunits (P2X1-7) all of which share the common structure of two transmembrane domains, a large extracellular loop and intracellular C- and N-termini. Receptors can be formed from triplets of identical subunits (homomeric) and can also exist as heteromers. With the exception of P2X6, all subunits can form homomeric receptors. P2X receptors have a wide distribution throughout the body, including the central, peripheral and autonomic nervous systems, smooth muscle, heart and leukocytes. They are involved in a range of physiological processes such as modulation of synaptic transmission, vascular tone, cardiac rhythm and contractility and nociception.
