Converts monoacylglycerides to free fatty acids and glycerol (PubMed:19029917, PubMed:20079333, PubMed:21049984, PubMed:22969151, PubMed:24368842). Hydrolyzes the endocannabinoid 2- arachidonoylglycerol, and thereby contributes to the regulation of endocannabinoid signaling, nociperception and perception of pain (PubMed:19029917, PubMed:20079333, PubMed:21049984, PubMed:22969151, PubMed:24368842). Regulates the levels of fatty acids that serve as signaling molecules and promote cancer cell migration, invasion and tumor growth (PubMed:20079333). {ECO:0000269|PubMed:19029917, ECO:0000269|PubMed:20079333, ECO:0000269|PubMed:21049984, ECO:0000269|PubMed:22969151, ECO:0000269|PubMed:24368842}. This is the function of Ensembl gene identifier ENSG00000074416 (MGLL, monoglyceride lipase).
