UniProtKB accession:  F8W463

Grouped By:  Matching UniProtKB accession

UniProtKB description:  ATP-gated nonselective transmembrane cation channel permeable to potassium, sodium and calcium (By similarity). CTP, but not GTP or UTP, functions as a weak affinity agonist for P2RX4 (PubMed:28332633). Activated by extracellularly released ATP, it plays multiple role in immunity and central nervous system physiology (By similarity). Could also function as an ATP-gated cation channel of lysosomal membranes (By similarity).
