| 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 of 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。 |
