ABHD12 is a 398-aa protein, with serine hydrolase activity. It has a molecular weight of ~45 kDa. A single TM is predicted at 75-95, with an extracellular catalytic domain. ABHD12 is a monoacylglycerol hydrolase [12], but may also regulate lysophosphatidylserine levels [8]. Loss-of-function mutations in ABHD12 are associated with a disorder known as PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataracts) [5].
