The hormone regulatory element (HRE) of mouse mammary tumor virus can mediate activation of an adjacent promoter by glucocorticoids and progestins. A detailed comparison of the DNA binding of receptors for both hormones using DNAase I footprinting and methylation protection detects clear differences in their interactions with the HRE region between(More)
In order to identify amino acids directly involved in progesterone binding to rabbit uteroglobin we have mutated Phe 6, Tyr 21 and Thr 60 by site-directed mutagenesis of the uteroglobin cDNA. These residues have been postulated previously to participate in progesterone binding. High-level expression of the mutated uteroglobin cDNAs in Escherichia coli(More)
