To identify proteins from uninduced murine erythroleukemia nuclear extracts which specifically bind to sequences from the DNase I-hypersensitive region within the mouse β-globin intervening sequence 2 (IVS2), a gel electrophoretic mobility shift assay was used. Two distinct sequence-specific binding proteins were detected. The specific binding sites for these factors were delineated by both DNase I protection footprinting and methylation interference. Factor B1 bound specifically to two homologous sites, B1-A and B1-B, approximately 100 base pairs apart within the IVS2 and on opposite strands. These two regions could interact with factor B1 independently. Factor B1 was limited to cells of hematopoietic lineages. Factor B2 bound to a site approximately 5 base pairs away from the B1-A site and was limited to cells of the erythroid lineage. The limited tissue distribution of these factors and the locations of their binding sites suggest that one or both of these factors may be involved in the formation of the tissue-specific DNase I-hypersensitive site in the IVS2 of the mouse β-globin gene.
