Background: The effects of progesterone are mediated by two functionally different isoforms of the progesterone receptor , PR-A and PR-B, which are transcribed from distinct, estrogen-inducible promoters within a single copy of the PR geneThe first 164 amino acids of PR-B are absent in PR-A. Progesteronebound PR-A and PR-B have different transcription activation properties. Specifically, PR-B functions as a transcriptional activator in most cell and promoter contexts, while PR-A is transcriptionally inactive and functions as a strong ligand-dependent transdominant repressor of steroid hormone receptor transcriptional activity. An inhibitory domain （ID）, which maps to the amino terminus of the receptor , exists within both PR isoforms. Interestingly, the ID is functionally active only in PR-A and is necessary for steroid hormone transrepression by PR-A, suggesting that PR-A and PR-B may have different conformations in the cell. Phosphorylation of human PR occurs on at least nine serine residues. Phosphorylation of three of the residues is hormoneinducible （Ser 102, Ser 294 and Ser 345）; the others are basal but hormonestimulated.
