孕酮受体（英語：，缩写PR，也被称为NR3C3 ，nuclear receptor subfamily 3, group C, member 3，即核受体第三亚族C组成员3）是一种细胞内蛋白质，由甾体激素孕酮激活。

在人体中，孕酮受体由基因PGR 编码，位于11号染色体长臂22区[1][2][3]，能通过选择性剪接形成两种蛋白异形体A和B，有着各自不同的分子量[4][5][6]。

功能

孕酮是引起孕酮受体反应的配体，在孕酮受体的C端未结合该激素时，与其相关的DNA片段的转录处于抑制状态。在与激素结合后，孕酮受体会变构并开始起作用。而孕酮受体的受体拮抗剂会阻止这种结构改变。

在孕酮与其受体结合后，孕酮受体变构并发生二聚化，紧接着以复合体形式进入细胞核与相关的DNA结合，从而使其开始转录，合成mRNA，并表达为相关蛋白质。

结构

和其它甾体激素受体类似，孕酮受体的N端有一个调控结构域，一个DNA结合结构域，以及一个铰链区，在C端有一个配体结合结构域。异形体B比异形体A多一个TAF-3区域。

交互作用

孕酮受体能与下列蛋白質发生交互作用：

KLF9[7]
Nuclear receptor co-repressor 2[8]
UBE3A[9]
