== Function == | |||
'''Progesterone receptor''' (PR) binds to DNA and inhibits transcription. It is [[Nuclear receptors|nuclear receptor]]. The inhibition terminates when progesterone binds to PR. The ovarian steroid progesterone which is essential for breast development and reproductive behavior, is mediated by PR<ref>PMID:19072517</ref>. | |||

The response to hormone therapy in breast cancer correlates with PR. PR absence in breast tumor cells predicts resistance to hormone therapy <ref>PMID:16234531</ref>. [[Mometasone]] is a potent agonist of PR<ref>PMID:15189034</ref>. | |||

The structure of the complex of the ligand-binding domain of PR with RU486 - an abortion-inducing drug - shows the ligand bound at a similar location to other agonists or partial agonists with a flexible loop of PR being a possible entry route to the <scene name='78/780972/Cv/4'>binding site and several PR-RU486 interactions</scene><ref>PMID:19372222</ref>. Water molecules are shown as red spheres. <scene name='89/895670/Cv/8'>Human progesterone receptor ligand-binding domain bound with progesterone</scene> ([[1a28]]). | |||
