Identification
HMDB Protein ID HMDBP07859
Secondary Accession Numbers
  • 13569
Name P2X purinoceptor 1
Synonyms
  1. ATP receptor
  2. P2X1
  3. Purinergic receptor
Gene Name P2RX1
Protein Type Unknown
Biological Properties
General Function Involved in receptor activity
Specific Function Ligand-gated ion channel with relatively high calcium permeability. Binding to ATP mediates synaptic transmission between neurons and from neurons to smooth muscle. Seems to be linked to apoptosis, by increasing the intracellular concentration of calcium in the presence of ATP, leading to programmed cell death
