The Yt blood group system comprises two antigens, Yta and Ytb. Human anti-Yta and human anti-Ytb immune precipitate a component of the same apparent molecular weight as acetylcholinesterase from radioiodinated erythrocytes of appropriate Yt phenotype. Immune precipitates obtained with anti-Yta and anti-Ytb contained acetylcholinesterase activity. In contrast, immune precipitates obtained with human anti-Gya and murine monoclonal anti-CD55, which identify other glycosylphosphatidylinositol-linked erythrocyte surface proteins, did not have acetylcholinesterase activity. Quantitative binding assays using murine monoclonal antiacetylcholinesterase antibodies (AE-1 and AE-2) gave 3,000 to 5,000 binding sites/cell for IgG and 7,000 to 10,000 sites/cell for Fab fragments. Endo F digestion of immune precipitates obtained with AE-1 and anti-Yta indicated that approximately 10% of the enzyme comprises N-glycans. These results indicate that the Yt antigens define an inherited polymorphism on erythrocyte acetylcholinesterase and that the recent assignment of the Yt blood group locus to the long arm of chromosome 7 (Zelinski et al, Genomics 11:165, 1991) provisionally identifies the position of the acetylcholinesterase gene.
