Involved in the lipid remodeling steps of GPI-anchor maturation. Lipid remodeling steps consist in the generation of 2 saturated fatty chains at the sn-2 position of GPI-anchors proteins. Required for phospholipase A2 activity that removes an acyl-chain at the sn-2 position of GPI-anchors during the remodeling of GPI.
Subcellular locations: Golgi apparatus membrane, Endoplasmic reticulum membrane
Mainly localizes to Golgi apparatus.
Ubiquitously expressed, with highest levels in thyroid and placenta.
