To investigate the role of NF-M in hematopoietic cell lineage commitment, we constructed a conditional form of the protein by fusing it to the hormone binding domain of the human estrogen receptor .
 cell line: hematopoietic cell lineage; protein: human estrogen receptor; protein: NF-M; protein: hormone binding domain
