General annotation (Comments)

Function

Receptor for ATP that acts as a ligand-gated ion channel.

Subunit structure

Functional P2XRs are organized as homomeric and heteromeric trimers By similarity.

Subcellular location

Membrane; Multi-pass membrane protein.

Tissue specificity

Expressed at high levels in brain and immune system.

Sequence similarities

Belongs to the P2X receptor family.

Sequence caution

The sequence AAF43106.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence AK307959 differs from that shown. Reason: Frameshift at position 112.

The sequence BAD92860.1 differs from that shown. Reason: Frameshift at position 112.

The sequence BC028084 differs from that shown. Reason: Frameshift at position 112.

Alternative products

This entry describes 5 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q93086-3)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q93086-1)

Also known as: A;

The sequence of this isoform differs from the canonical sequence as follows:
     205-206: KS → N
Isoform 3 (identifier: Q93086-2)

Also known as: B;

The sequence of this isoform differs from the canonical sequence as follows:
     97-120: Missing.
     205-206: KS → N
Isoform 4 (identifier: Q93086-4)

The sequence of this isoform differs from the canonical sequence as follows:
     421-422: ST → LRTPSASPLHQE
Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.
Isoform 5 (identifier: Q93086-5)

The sequence of this isoform differs from the canonical sequence as follows:
     97-120: Missing.
