MODE OF ACTION OF STEROID HORMONES

描述（改编自申请人摘要）：本提案 重点研究糖皮质激素受体（GR） GR通过磷酸化的功能和动态转化， 与热休克蛋白的关系校长以前的工作 研究者已经详细确定了GR发生的部位， 磷酸化，并显示GR的细胞周期依赖性变化 磷酸化和热休克蛋白缔合/解离。 的 目前的建议将扩展这些研究，解决1）GR的作用 GR功能中的磷酸化; 2）细胞周期依赖性的作用 3）雌激素在这种磷酸化中的可能性， 孕酮受体也穿越ATP依赖性周期。

DESCRIPTION (Adapted from the applicant's abstract): This proposal focuses on the relationship between glucocorticoid receptor (GR) function and dynamic transformations of GR by phosphorylation and association with heat shock proteins. Previous work by the principal investigator has identified in detail the sites at which GR is phosphorylated, and has shown cell-cycle dependent changes in GR phosphorylation and heat shock protein association/dissociation. The present proposal will extend these studies, addressing 1) the role of GR phosphorylation in GR function; 2) the role of cell-cycle dependent kinases in this phosphorylation; 3) the possibility that estrogen in progesterone receptors also traverse ATP-dependent cycles.
