PR-A lacks the first 164 amino acid residues of PR-B (1,2). Both PR-A and PR-B are ligand activated, but differ in their relative ability to activate target gene transcription (3,4). The activity of PR is regulated by phosphorylation; at least seven serine residues are phosphorylated in its amino-terminal domain. Three sites (Ser81, Ser102, and Ser162) are unique to full length PR-B, while other sites (Ser190, Ser294, Ser345, and Ser400) are shared by both isoforms (5). Phosphorylation of PR-B at Ser190 (equivalent to Ser26 of PR-A) is catalyzed by CDK2 (6). Mutation of Ser190 results in decreased activity of PR (7), suggesting that the phosphorylation at Ser190 may be critical to its biological function.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nNR3C3; Nuclear receptor subfamily 3 group C member 3; PGR; PR; PRGR; Progesterone receptor\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800445538473,"sku":"55652S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-55652s","provider":"Iright","version":"1.0","type":"link"}
