The human androgen receptor (hAR) is a member of the nuclear receptor superfamily and functions as a ligand-inducible transcription factor. We have previously proposed that c-Jun mediates the transcriptional activity of this receptor. The modular nature of hAR was used in this study to generate several fusions with the heterologous DNA-binding domain of the yeast transcription factor GAL4 in an attempt to identify the c-Jun-responsive domains within the receptor. Our results suggest that the target of c-Jun action is the amino terminus (AB region) of the receptor and that hAR amino acids 502-521 are critical for the c-Jun response. Additionally, amino acids 503-555 were shown to harbor an autonomous transactivation that is stimulated by c-Jun. Furthermore, we demonstrated that transcription intermediary factor-2 (TIF-2), a coactivator that acts on the activation function-2, stimulates the full-length hAR. These results suggest that c-Jun and TIF-2 can work together as coactivators on the hAR by targeting distinct portions of the receptor.
