The requirement of activation function domain-2 (AF-2) for hER to interact with RBP4 was also detected by the yeast two hybrid assay. The results show that RBP4 could interact with many nuclear receptors including mouse estrogen receptor related receptor 3 (mERR3), retinoid X receptor (RXR), glucocorticoid receptor (GR), progestin receptor (PR), and androgen receptor (AR) in yeast cells. Over-expressed RBP4 could strongly enhance the trans-activation functions of hERR1 and hER in a dose-dependent manner, respectively. RBP4 could also interact with hER in an AF-2-dependent manner.展开更多
