Protein Structure
UniProt Annotation
Function 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 (Probable). {ECO:0000305PubMed:17021251}.
Subcellular Localization Golgi apparatus membrane {ECO:0000305PubMed:12460457}; Multi-pass membrane protein {ECO:0000305PubMed:12460457}. Endoplasmic reticulum membrane {ECO:0000305PubMed:12460457}; Multi-pass membrane protein {ECO:0000305PubMed:12460457}. Note=Mainly localizes to Golgi apparatus. {ECO:0000305}.
Disease Associations Hyperphosphatasia with mental retardation syndrome 4 (HPMRS4) [MIM:615716]: An autosomal recessive neurologic disorder characterized by profound developmental delay, severe mental retardation, no speech, psychomotor delay, postnatal microcephaly, and elevated serum alkaline phosphatase. {ECO:0000269PubMed:24439110}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Ubiquitously expressed, with highest levels in thyroid and placenta. {ECO:0000269PubMed:12460457}.
