The function of ABHD6 (abhydrolase domain containing 6, acylglycerol lipase, Ensembl gene identifier ENSG00000163686) is as follows. Lipase that preferentially hydrolysis medium-chain saturated monoacylglycerols including 2-arachidonoylglycerol (PubMed:22969151). Through 2-arachidonoylglycerol degradation may regulate endocannabinoid signaling pathways (By similarity). Also has a lysophosphatidyl lipase activity with a preference for lysophosphatidylglycerol among other lysophospholipids (By similarity). Also able to degrade bis(monoacylglycero)phosphate (BMP) and constitutes the major enzyme for BMP catabolism (PubMed:26491015). BMP, also known as lysobisphosphatidic acid, is enriched in late endosomes and lysosomes and plays a key role in the formation of intraluminal vesicles and in lipid sorting (PubMed:26491015). {ECO:0000250|UniProtKB:Q8R2Y0, ECO:0000269|PubMed:22969151, ECO:0000269|PubMed:26491015}.
