General annotation (Comments)

Function

Receptor for ATP that acts as a ligand-gated ion channel. Responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells.

Subunit structure

Forms homo- or heteropolymers. Interacts with LAMA3, ITGB2, ACTB, ACTN4, SVIL, MPP3, HSPA1, HSPCB, HSPA8, PIK230 and PTPRB. Ref.5

Subcellular location

Membrane; Multi-pass membrane protein.

Post-translational modification

Phosphorylation results in its inactivation.

ADP-ribosylation at Arg-125 is necessary and sufficient to activate P2RX7 and gate the channel By similarity.

Sequence similarities

Belongs to the P2X receptor family.
