|Application ||WB, IHC|
|Calculated MW||98981 Da|
|Other Names||Progesterone receptor, PR, Nuclear receptor subfamily 3 group C member 3, PGR, NR3C3|
|Target/Specificity||A synthetic peptide corresponding to residues near N-terminus of human Progesterone Receptor was used as immunogen. The antibody does not cross-react with other NR3 family members.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Progesterone Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Progesterone receptor isoform B (PRB) is involved activation of c-SRC/MAPK signaling on hormone stimulation. Isoform 4: Increases mitochondrial membrane potential and cellular respiration upon stimulation by progesterone.|
|Cellular Location||Nucleus. Cytoplasm. Note=Nucleoplasmic shuttling is both homone- and cell cycle-dependent. On hormone stimulation, retained in the cytoplasm in the G(1) and G(2)/M phases Isoform 4: Mitochondrion outer membrane|

The human progesterone receptor (PR), is a ligand-activated transcription factor and is a member of the steroid receptor family (1). PR exists in humans as two isoforms; PR-A (94 kDa) which lacks the first 164 amino acids of PR-B and PR-B (114 kDa)(2-3). While the two forms of PR have similar DNA- and ligand-binding affinities they have opposite transcriptional activities. PR-B functions as an activator of progesterone-responsive genes, while PR-A functions as a strong transdominant repressor of PR-B (4)
