Human glycophorin A and B are encoded by separate, single copy genes coordinately regulated by a tumor-promoting phorbol ester.

Abstract Human glycophorin A belongs to a family of structurally related cell surface glycoproteins which are expressed in erythroid cells. We have recently isolated several human glycophorin A-specific cDNA clones and have determined their nucleotide sequence (Siebert, P. D., and Fukuda, M. (1986) Proc. Natl. Acad. Sci. U. S. A. 83, 1665-1669). In this report by using cDNA and exact sequence synthetic oligodeoxyribonucleotides as hybridization probes, we provide evidence that human glycophorin A and B are encoded by separate and distinct genes present as single copies in the human genome. Furthermore, we show that the expression of the glycophorin A and B genes are coordinately regulated by tumor-promoting phorbol ester, 12-O-tetradecanoylphorbol-13-acetate.
