Identification of ABHD6 as a lysophosphatidylserine lipase in the mammalian liver and kidneys.

ABSTRACT: Lysophosphatidylserine (lyso-PS) is a potent hormone-like signaling lysophospholipid, which regulates many facets of mammalian biology and dysregulation in its metabolism is associated with several human neurological and autoimmune diseases. Despite the physiological importance and causal relation with human pathophysiology, little is known about the metabolism of lyso-PS in tissues other than the nervous and immune systems. To address this problem, here, we attempted to identify one (or more) lipase(s) capable of degrading lyso-PS in different mammalian tissues. We found that the membrane fraction of most mammalian tissues possess lyso-PS lipase activity, yet interestingly, the only bona fide lyso-PS lipase ABHD12 displays this enzymatic activity and has control over lyso-PS metabolism on
