Overview
P2X1 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. Belongs to the P2X receptor family. Note: This description may include information from UniProtKB.
Protein type: Membrane protein, integral; Membrane protein, multi-pass; Channel, ligand-gated
Chromosomal Location of Human Ortholog: 17p13.3
Cellular Component: postsynaptic membrane; neuron projection; protein complex; integral to plasma membrane; plasma membrane; integral to nuclear inner membrane; lipid raft
Molecular Function: zinc ion binding; calcium channel activity; cation channel activity; drug binding; purinergic nucleotide receptor activity; ATP binding; ATP-gated cation channel activity
Biological Process: caspase activation; vasoconstriction; synaptic transmission, glutamatergic; platelet activation; protein heterooligomerization; insemination; generation of action potential; regulation of calcium ion transport; signal transduction; response to ATP; transport; serotonin secretion by platelet; regulation of blood pressure; regulation of vascular smooth muscle contraction; ceramide biosynthetic process; ion transport; positive regulation of ion transport; blood coagulation; cation transport; protein homooligomerization
