| Enzyme Function | FUNCTION: Serine hydrolase that hydrolyzes arachidonic acid-esterified diacylglycerols (DAGs) to produce the principal endocannabinoid, 2-arachidonoylglycerol (2-AG). Preferentially hydrolyzes sn-1 fatty acids from diacylglycerols (DAG) that contain arachidonic acid (AA) esterified at the sn-2 position to biosynthesize 2-AG. Has negligible activity against other lipids including monoacylglycerols and phospholipids. Plays a key role in regulating 2-AG signaling in the CNS. Controls the activity of 2-AG as a retrograde messenger at neuronal synapses. Supports axonal growth during development and adult neurogenesis. Plays a role for eCB signaling in the physiological regulation of anxiety and depressive behaviors. Regulates also neuroinflammatory responses in the brain, in particular, LPS-induced microglial activation. {ECO:0000250|UniProtKB:Q6WQJ1}. |
