function:Essential for GPI-anchoring of precursor proteins but not for GPI synthesis. Acts before or during formation of the carbonyl intermediate.,pathway:Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis.,sequence caution:Erroneous prediction from an unspliced cDNA.,subunit:Forms a complex with PIGK/GPI8, PIGT, PIGU and PIGS.,tissue specificity:Ubiquitously expressed in fetal and adult tissues. Expressed at higher levels in fetal tissues than adult tissues.,
Endoplasmic reticulum membrane ; Multi-pass membrane protein .
Ubiquitously expressed in fetal and adult tissues. Expressed at higher levels in fetal tissues than adult tissues.
