Protein attributes
| Sequence length | 472 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in cannabinoid-induced CNS effects. Acts by inhibiting adenylate cyclase. Could be a receptor for anandamide. Inhibits L-type Ca2+ channel current. Isoform 2 and isoform 3 have altered ligand binding. Ref.4 |
| Subunit structure | Interacts (via C-terminus) with CNRIP1. Ref.13 |
| Subcellular location | |
| Tissue specificity | Widely expressed. Ref.4 |
| Post-translational modification | Palmitoylation at Cys-415 is important for recruitment at both plasma membrane and lipid rafts. Ref.14 |
| Sequence similarities | Belongs to the G-protein coupled receptor 1 family. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: P21554-1) Also known as: Long; 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: P21554-2) Also known as: CB1a,Short; The sequence of this isoform differs from the canonical sequence as follows: 1-89: MKSILDGLAD...EFYNKSLSSF → MALQIPPSAPSPLTSCTWAQMTFSTKTS | ||||||
| Isoform 3 (identifier: P21554-3) Also known as: CB1b; The sequence of this isoform differs from the canonical sequence as follows: 22-54: Missing. |
