P2rx4 Gene Summary [Mouse]
Enables extracellularly ATP-gated monoatomic cation channel activity. Acts upstream of or within several processes, including excitatory postsynaptic potential; nitric oxide biosynthetic process; and vasodilation. Located in apical part of cell. Is active in lysosomal membrane. Is expressed in several structures, including cardiovascular system; gut; immune system; nervous system; and viscerocranium. Orthologous to human P2RX4 (purinergic receptor P2X 4). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse P2rx4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
