Protein: P2X purinoceptor 6 (P2X6) (ATP receptor) (P2XM) (Purinergic receptor) (Purinergic receptor P2X-like 1) (P51579)
Organism: Rattus norvegicus (Rat)
Function: Receptor for ATP that acts as a ligand-gated ion channel.
Subcellular location: Cell membrane {ECO:0000269|PubMed:15044628, ECO:0000269|PubMed:16452399}; Multi-pass membrane protein {ECO:0000255}. Endoplasmic reticulum {ECO:0000269|PubMed:12077178, ECO:0000269|PubMed:16452399}. Nucleus {ECO:0000250|UniProtKB:O54803}. Nucleus inner membrane {ECO:0000250|UniProtKB:O54803}; Multi-pass membrane protein {ECO:0000255}. Note=Monomers remain anchored to the endoplasmic reticulum (ER) membrane by the hydrophobic N-terminal end (PubMed:12077178, PubMed:15044628, PubMed:16452399). Heteromerization of P2RX6 subunits with either P2RX2 or P2RX4 subunits guides the P2RX6 subunit to the plasma membrane (PubMed:16452399). Retention of P2RX6 subunit in the ER allows it to reach the nucleus (PubMed:16452399). In neurons, mainly expressed in the cell body of the hippocampal neurons (By similarity). {ECO:0000250|UniProtKB:O54803, ECO:0000269|PubMed:12077178, ECO:0000269|PubMed:15044628, ECO:0000269|PubMed:16452399}.
