Preparation and Storage

Background: Progesterone R/NR3C3

Progesterone Receptor B (PR-B) is a 118 kDa member of the NR3 subfamily within the nuclear hormone receptor family of proteins. It is expressed in female reproductive tissues as well as neurons throughout the CNS. PR-B is particularly important in the mammary gland where it mediates proliferative responses to progesterone. Human PR-B is 933 amino acids (aa) in length. It contains an N-terminal regulatory region (aa 1‑566), a DNA binding domain (aa 567‑639), and a
steroid-binding region (aa 681‑933). Ligand binding induces a key phosphorylation event at Ser294 by ERK1/2. An alternate start site at Met165 generates 90 kDa
PR‑A, an isoform particularly important in the ovary and uterus that insures fertility. Other isoforms show a deletion of either aa 637‑738 or 598‑636, or a 17 aa substitution for aa 787‑933.
