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