背景 | Human progesterone receptor (PR) is expressed as two forms: the full length PR-B and the short form PR-A. 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.人孕酮受体(PR)表现为两种形式:全长的孕酮受体B和短的孕酮受体A。PR A缺少PR B的第164个氨基酸残基(1,2)。PR A和PR B都是配体激活,但其激活靶基因转录的相对能力是不同的(3,4)。PR的活性受磷酸化调节。在其氨基末端区域,至少有七个丝氨酸残基被磷酸化。丝氨酸三个位点(81,102,162位)是全长PR特有的,而其他丝氨酸位点(190,294,345和400位)是两个亚型所共有的(5)。PR B丝氨酸(190位)(相当于PR A丝氨酸(26位))的磷酸化是由CDK2催化的(6)。丝氨酸(190位)的突变导致PR活性降低(7),这表明丝氨酸(190位)的磷酸化对其生物功能来说是至关重要的。 |
