Monoacylglycerol lipase (MGL/MAGL/MGLL) is a serine hydrolase involved in the biological deactivation of the endocannabinoid 2-arachidonoyl-sn-glycerol (2-AG). 2-AG is the most abundant endogenous lipid agonists for cannabinoid receptors in the brain and elsewhere in the body. In the central nervous system (CNS), MGL is localized to presynaptic nerve terminals of both excitatory and inhibitory synapses, where it controls the regulatory actions of 2-AG on synaptic transmission and plasticity. In this chapter, we describe an in vitro method to assess MGL activity by liquid chromatography/mass spectrometry (LC/MS)-based quantitation of its reaction product. The method may be used to determine basal or altered MGL activity in cells or tissues after pharmacological, genetic, or biological interventions. In addition, the assay can be used for MGL inhibitor screening using purified recombinant enzyme or MGL-overexpressing cells.

D012694	Serine	A non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. It is involved in the biosynthesis of PURINES; PYRIMIDINES; and other amino acids.	L-Serine,L Serine
D043882	Receptors, Cannabinoid	A class of G-protein-coupled receptors that are specific for CANNABINOIDS such as those derived from CANNABIS. They also bind a structurally distinct class of endogenous factors referred to as ENDOCANNABINOIDS. The receptor class may play a role in modulating the release of signaling molecules such as NEUROTRANSMITTERS and CYTOKINES.	Cannabinoid Receptor,Cannabinoid Receptors,Receptor, Cannabinoid
D063388	Endocannabinoids	Fatty acid derivatives that have specificity for CANNABINOID RECEPTORS. They are structurally distinct from CANNABINOIDS and were originally discovered as a group of endogenous CANNABINOID RECEPTOR AGONISTS.	Endocannabinoid
