UniprotKB/SwissProt ID: Q9JJX6 (Q9JJX6)
Gene Name:
P2rx4
Organism: Mus musculus (Mouse)
Function: ATP-gated nonselective transmembrane cation channel permeable to potassium, sodium and calcium. CTP, but not GTP or UTP, functions as a weak affinity agonist for P2RX4 (By similarity). Activated by extracellularly released ATP, it plays multiple role in immunity and central nervous system physiology (PubMed:26456657, PubMed:35119925). Plays a key role in initial steps of T-cell activation and Ca(2+) microdomain formation (PubMed:35119925). Also participates in basal T-cell activity without TCR/CD3 stimulation (PubMed:35119925). Promotes the differentiation and activation of Th17 cells via expression of retinoic acid-related orphan receptor C/RORC (By similarity). Upon activation, drives microglia motility via the PI3K/Akt pathway (PubMed:17299767). Could also function as an ATP-gated cation channel of lysosomal membranes (PubMed:27477609)
