Detection of Human Progesterone R B/NR3C3 by Western Blot. Western blot shows lysates of T47D human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Human Progesterone R B/NR3C3 Monoclonal Antibody (Catalog # MAB5886) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Progesterone R B/NR3C3 at approximately 118 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Background: Progesterone R B/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 several tissues, including female reproductive organs 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 contains an N-terminal regulatory region (aa1‑566), 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.
