Sulfotransferase 1E1 sequence variants
View Patent ↗Isolated sulfotransferase nucleic acid molecules that include a nucleotide sequence variant and nucleotides flanking the sequence variant are described, as well as sulfotransferase allozymes. Methods for determining if a mammal is predisposed to cancer also are described.
1. An isolated human sulfotransferase 1E1 (SULT1E1) polypeptide comprising the amino acid sequence set forth in SEQ ID NO:7, wherein the amino acid sequence has a variation at residue 32 of SEQ ID NO:7.
2. The isolated SULT1E1 polypeptide of claim 1 , wherein the amino acid sequence variant at residue 32 of SEQ ID NO:7 is a valine substitution for alanine.
3. The isolated polypeptide of claim 1 , wherein sulfotransferase activity of the polypeptide is altered relative to a wild type SULT1E1 polypeptide.
