Pancreatic lipase related protein 2 (or PLRP2) is an enzyme that in humans is encoded by the PNLIPRP2gene. PLRP2 is a digestive enzyme and lipase that is found in pancreatic juice. Nonsense mutations in PNLIPRP2 (eg: W358X) are very common in certain ethnic groups, with allele frequencies as high as 30-50%, and notably the allele in the reference genome is a non-coding allele.
PLRP2 is part of the pancreatic lipase family.
Function
Like many lipases, one of PLRP2's main functions is to break down triglycerides. However, it is distinct from other lipases found in humans by being able to act on galactosylglycerides, making it a galactolipase. Since the primary digestive lipase, pancreatic lipase, is not expressed in newborn human babies, it is thought that PLRP2 may play a role in their digestion of lipids.
