Purinergic receptor P2X, ligand-gated ion channel, 6
P2X6, P2X6 receptor, P2XM
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] (from

The P2X(6) receptors are mainly expressed on intrinsic sensory neurons and that ATP, via P2X(6) receptors probably in heteromeric combination with P2X(2) receptors, may be involved in regulating the physiological functions of these neurons.
