Monoacylglycerol lipase, also known as MAG lipase, MAGL, MGL or MGLL is a protein that, in humans, is encoded by the ''MGLL'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=11343 )〕 MAGL is a 33-kDa, membrane-associated member of the serine hydrolase superfamily and contains the classical GXSXG consensus sequence common to most serine hydrolases. The catalytic triad has been identified as Ser122, His269, and Asp239.〔 ==Function==
Monoacylglycerol lipase functions together with hormone-sensitive lipase (LIPE) to hydrolyze intracellular triglyceride stores in adipocytes and other cells to fatty acids and glycerol. MGLL may also complement lipoprotein lipase (LPL) in completing hydrolysis of monoglycerides resulting from degradation of lipoprotein triglycerides. Monoacylglycerol lipase is a key enzyme in the hydrolysis of the endocannabinoid 2-arachidonoylglycerol. It converts monoacylglycerols to the free fatty acid and glycerol. The contribution of MAGL to total brain 2-AG hydrolysis activity has been estimated to be ~85%, and this ''in vitro'' estimate has been confirmed ''in vivo'' by the selective MAGL inhibitor JZL184.
