Protein: Diacylglycerol lipase-alpha (DAGL-alpha) (DGL-alpha) (EC 3.1.1.116) (Neural stem cell-derived dendrite regulator) (Sn1-specific diacylglycerol lipase alpha) (Q6WQJ1)
Organism: Mus musculus (Mouse)
Function: Serine hydrolase that hydrolyzes arachidonic acid-esterified diacylglycerols (DAGs) to produce the principal endocannabinoid (eCB), 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 central nervous system (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.
Subcellular location: Cell membrane {ECO:0000269|PubMed:17584991}; Multi-pass membrane protein {ECO:0000255}. Cell projection, dendritic spine membrane {ECO:0000269|PubMed:16723519}; Multi-pass membrane protein {ECO:0000255}. Postsynaptic density membrane {ECO:0000250|UniProtKB:Q9Y4D2}; Multi-pass membrane protein {ECO:0000255}. Early endosome membrane {ECO:0000250|UniProtKB:Q9Y4D2}; Multi-pass membrane protein {ECO:0000255}. Note=Cycles between the cell surface and an intracellular endosomal compartment. Internalized by early endosomes via a clathrin-independent pathway before transport back to the postsynaptic membrane surface in a PKC-dependent manner. {ECO:0000250|UniProtKB:Q9Y4D2}.
