    摘要: The present invention relates to the novel isoforms, RXRα2 and RXRα3, of nuclear receptor RXRα. Unlike known isoform RXRα1, the transcriptional activation functions of RXRα2 and RXRα3 are augmented by SRC-1. The present invention provides methods for evaluating the function of regulating augmentation by co-activators of these RXRα isoforms, and screening methods based on these evaluation methods. By controlling the interaction between isoforms and co-activators, transcription-controlling activity can be regulated in an isoform-specific manner.
