Human Gene ABHD12 (ENST00000339157.10) from GENCODE V44
  Description: Homo sapiens abhydrolase domain containing 12, lysophospholipase (ABHD12), transcript variant 1, mRNA. (from RefSeq NM_001042472)
RefSeq Summary (NM_001042472): This gene encodes an enzyme that catalyzes the hydrolysis of 2-arachidonoyl glycerol (2-AG), the main endocannabinoid lipid transmitter that acts on cannabinoid receptors, CB1 and CB2. The endocannabinoid system is involved in a wide range of physiological processes, including neurotransmission, mood, appetite, pain appreciation, addiction behavior, and inflammation. Mutations in this gene are associated with the neurodegenerative disease, PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract), resulting from an inborn error of endocannabinoid metabolism. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jan 2011].

-  Comments and Description Text from UniProtKB
  ID: ABD12_HUMAN
DESCRIPTION: RecName: Full=Monoacylglycerol lipase ABHD12; EC=3.1.1.23; AltName: Full=2-arachidonoylglycerol hydrolase; AltName: Full=Abhydrolase domain-containing protein 12;
FUNCTION: Has 2-arachidonoylglycerol hydrolase activity (By similarity). May be a regulator of endocannabinoid signaling pathways (By similarity).
CATALYTIC ACTIVITY: Hydrolyzes glycerol monoesters of long-chain fatty acids.
SUBCELLULAR LOCATION: Membrane; Single-pass membrane protein (By similarity).
PTM: Glycosylated (By similarity).
DISEASE: Defects in ABHD12 are the cause of polyneuropathy hearing loss ataxia retinitis pigmentosa and cataract (PHARC) [MIM:612674]. PHARC is a slowly progressive neurologic disorder with a variable phenotype resembling Refsum disease. Clinical features include sensorineural hearing loss, visual problems related to cataracts, retinitis pigmentosa, pes cavus, ataxic and/or spastic gait disturbances with a progressive sensorimotor peripheral neuropathy. Other features include hyporeflexia, hyperreflexia, extensor plantar responses.
SIMILARITY: Belongs to the serine esterase family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
