Sequence data for the sheep .alpha.(1,3)galactosyltransferase (.alpha.1,3GT) gene is provided in this disclosure, which allows the user to construct vectors for expressing or inactivating the .alpha.1,3GT gene. This in turn enables the user to control expression of the Gal.alpha.(1,3)Gal xenoantigen on the surface of cells.
