An erythroid nuclear protein (EF1), originally detected as a protein binding within the nuclease hypersensitive site upstream of the chicken beta H-globin gene, has been purified. This protein of 37,000-39,000 molecular weight binds to three sites within the hypersensitive region: one between the CCAAT and TATA boxes, the second (further upstream) next to a NF1 binding site, and the third adjacent to a regulatory element found in a number of beta-globin genes. The EF1 protein also binds to an erythroid-specific promoter element of the mouse alpha-globin gene and to two sites within the chicken beta A-globin enhancer. These six EF1-binding sites are related by the consensus sequence A/TGATAA/GG/C. A minor protein of molecular weight 72,000 which co-purifies with EF1 also binds to the same sequences. 相似文献

The product of the START gene CDC25, an upstream element of the RAS/adenylyl cyclase pathway in Saccharomyces cerevisiae, was identified using specific antibodies raised against a chimeric beta-galactosidase/CDC25 protein. The CDC25 protein is poorly expressed and can be detected only when the CDC25 gene is overexpressed under the control of the galactose-inducible GAL1-10 strong promoter elements. It has a molecular weight of 180,000, is not glycosylated and is strongly associated with the particulate fraction. After deletion of residues 1255-1550 the protein is found in the soluble fraction. 相似文献
