Protein attributes
| Sequence length | 672 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Catalyzes the hydrolysis of diacylglycerol (DAG) to 2-arachidonoyl-glycerol (2-AG), the most abundant endocannabinoid in tissues. Required for axonal growth during development and for retrograde synaptic signaling at mature synapses. Ref.8 |
| Cofactor | Calcium. Ref.8 |
| Enzyme regulation | Inhibited by p-hydroxy-mercuri-benzoate and HgCl2, but not to PMSF. Also inhibited by RHC80267, a drug that blocks 2-AG formation. Ref.8 |
| Subcellular location | |
| Sequence similarities | Belongs to the AB hydrolase superfamily. Lipase family. |
| Biophysicochemical properties | Kinetic parameters: KM=74.1 µM for diacylglycerol Ref.8 Vmax=3.45 nmol/min/mg enzyme pH dependence: Optimum pH is 7.0. |
| Sequence caution | The sequence BAB85017.1 differs from that shown. Reason: Erroneous initiation. |
