General annotation (Comments)

Function

Receptor for glutamate. The activity of this receptor is mediated by a G-protein that inhibits adenylate cyclase activity.

Subunit structure

Interacts with PICK1 By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Tissue specificity

Strongly expressed in the cerebellum. Expressed at low levels in hippocampus, hypothalamus and thalamus. No expression detected in liver.

Sequence similarities

Belongs to the G-protein coupled receptor 3 family.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q14833-1)

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: Q14833-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-33: MPGKRGLGWWWARLPLCLLLSLYGPWMPSSLGK → MVQTLPKLFPHDGAKRKKRTLRTSGPCFGGGGQ
     34-173: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: Q14833-3)

The sequence of this isoform differs from the canonical sequence as follows:
     1-172: MPGKRGLGWW...IMVANILRLF → MSC
