  • Function
    Ion channel gated by extracellular ATP involved in a variety of cellular responses, such as excitatory postsynaptic responses in sensory neurons, neuromuscular junctions (NMJ) formation, hearing, perception of taste and peristalsis. In the inner ear, regulates sound transduction and auditory neurotransmission, outer hair cell electromotility, inner ear gap junctions, and K(+) recycling. Mediates synaptic transmission between neurons and from neurons to smooth muscle.
  • Involvement in disease
    Deafness, autosomal dominant, 41
  • Sequence similarities
    Belongs to the P2X receptor family.
  • Cellular localization
    Cell membrane. Localizes to the apical membranes of hair cells in the organ of Corti.
  • Information by UniProt
  • Database links
  • Form
    There are 7 isoforms produced by alternative splicing.
