一般描述
Progesterone receptor (UniProt P06401; also known as nuclear receptor subfamily 3 group C member 3, PR) is encoded by the PGR (also known as NR3C3) gene (Gene ID 5241) in human. The progesterone receptor (PR) is a hormone activated transcription factor, where hormone binding triggers the dissociation of heat shock and chaperone proteins from PR, leading to PR dimerization and activation. The receptor dimer then binds progestin response elements in the regulatory regions of its target genes and a multi-component complex is assembled to enable transcription. In addition, a number of kinases are reported to regulate PR activity via phosphorylation. PR can also regulate transcription without direct DNA binding by tethering to other transcription factors, such as specificity protein 1 (Sp1) or activator protein 1 (AP-1), and modulating their transcriptional activity on target genes. PR is expressed as five isoforms, including PR-B and PR-A that are produced as a result of alternate estrogen inducible promoters within the same PGR gene. PR-A lacks the first 164 amino acids of PR-B, but the two isoforms have otherwise identical sequence. PR-B and PR-A can regulate distinct subsets of target genes and studies in knockout mice suggest that PR-B predominantly regulates mammary gland development and PR-A is critical for normal uterine function.
特异性
Clone 488/H3 reacts with both isoform 1 (isoform B; PR-B) and isoform 2 (isoform A; PR-A). This clone is also expected to react with isoform 5 (delta4), but not isoform 3 or 4 (PR-M).
免疫原
Recombinant protein corresponding to the N-terminal half fragment of human Progesterone Receptor B.
应用
This Anti-Progesterone Receptor A/B Antibody, clone 488/H3 is validated for use in Western Blotting and Immunocytochemistry for the detection of Progesterone Receptor A/B.
