Patent ID: 6936254

Claim:
A method comprising the steps of inducing a switch from adult hemoglobin to fetal hemoglobin in a cell comprising contacting said cell with a hemoglobin inducing polypeptide encoded by a nucleic acid comprising: a) a nucleic acid sequence encoding the hemoglobin inducing polypeptide shown in FIG. 4 (SEQ ID NO:7); b) a nucleic acid sequence encoding the hemoglobin inducing polypeptide shown in FIG. 4 (SEQ ID NO:7), lacking its associated signal peptide; c) a nucleic acid shown in FIG. 3 (SEQ ID NO:6); d) a full-length coding sequence of the nucleic acid sequence shown in FIG. 3 (SEQ ID NO:6); or e) a full-length coding sequence of the cDNA deposited under ATCC accession number 209508.
