Enables acylglycerol lipase activity and phospholipase activity. Involved in several processes, including monoacylglycerol catabolic process; negative regulation of cold-induced thermogenesis; and phospholipid metabolic process. Acts upstream of or within long-term synaptic depression; negative regulation of cell migration; and regulation of endocannabinoid signaling pathway. Located in late endosome membrane; lysosomal membrane; and mitochondrion. Is integral component of postsynaptic membrane. Part of AMPA glutamate receptor complex. Is active in GABA-ergic synapse and glutamatergic synapse. Orthologous to human ABHD6 (abhydrolase domain containing 6, acylglycerol lipase). [provided by Alliance of Genome Resources, Apr 2022]
