Names and origin
| Protein names | Recommended name: Metabotropic glutamate receptor 7 Short name=mGluR7 | ||||
| Gene names |
| ||||
| Organism | Homo sapiens (Human) [Complete proteome] | ||||
| Taxonomic identifier | 9606 [NCBI] | ||||
| Taxonomic lineage | Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo |
Protein attributes
| Sequence length | 915 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level. |
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 | |
| Tissue specificity | Expressed in many areas of the brain, especially in the cerebral cortex, hippocampus, and cerebellum. Expression of GRM7 isoforms in non-neuronal tissues appears to be restricted to isoform 3 and isoform 4. Ref.4 |
| Sequence similarities | Belongs to the G-protein coupled receptor 3 family. |
Ontologies
Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q14831-1) Also known as: GRM7_v1; mGluR7a; 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: Q14831-2) Also known as: GRM7_v2; mGluR7b; The sequence of this isoform differs from the canonical sequence as follows: 900-915: SPAAKKKYVSYNNLVI → NCIPPVRKSVQKSVTWYTIPPTV | ||||||
| Isoform 3 (identifier: Q14831-3) Also known as: GRM7_v3; The sequence of this isoform differs from the canonical sequence as follows: 900-915: SPAAKKKYVSYNNLVI → NFFFGCTVELGLHFKLTFSRNQSNL | ||||||
| Isoform 4 (identifier: Q14831-4) Also known as: GRM7_v4; The sequence of this isoform differs from the canonical sequence as follows: 900-915: SPAAKKKYVSYNNLVI → ITSEDLSLHKED | ||||||
| Isoform 5 (identifier: Q14831-5) Also known as: GRM7_v5; The sequence of this isoform differs from the canonical sequence as follows: 900-915: SPAAKKKYVSYNNLVI → SEKCNCY |
