Abstract
Previous attempts to express glycosylphosphatidylinositol-anchored pro teins in Ltk- cells have not been successful because Ltk- cells cannot synthesize N-acetylglucosamine-phosphatidylinositol, the first interm ediate in anchor biosynthesis. Using complementation cloning, we have identified a human cDNA that corrects the defect in anchor biosynthesi s and allows the expression of glycosylphosphatidylinositol-anchored p roteins in Ltk- cells. The nucleotide sequence predicts a novel cytoso lic protein of 188 amino acids.
