Summaries for ABHD12 Gene

Entrez Gene Summary for ABHD12 Gene

  • 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]

GeneCards Summary for ABHD12 Gene

ABHD12 (Abhydrolase Domain Containing 12) is a Protein Coding gene. Diseases associated with ABHD12 include polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract and polyneuropathy. Among its related pathways are triacylglycerol degradation. GO annotations related to this gene include acylglycerol lipase activity. An important paralog of this gene is ABHD12B.

UniProtKB/Swiss-Prot for ABHD12 Gene

  • Lysophosphatidylserine (LPS) lipase that plays a key role in the central nervous system. Represents a major LPS lipase in the brain (By similarity). May also have a 2-arachidonoylglycerol (2-AG) hydrolase activity and act as a regulator of endocannabinoid signaling pathways.
