abstractText | PIAS3, a member of the protein inhibitor of activated STAT family, was found to interact in vivo and in vitro with TIF2, a previously described coactivator for nuclear receptors. The interaction is mediated by two distinct non-contiguous regions of TIF2. We found that TIF2-PIAS3 interaction occurs through a unique domain of PIAS3, very rich in acidic residues and conserved throughout the PIAS family. PIAS3 modulates the ability of TIF2 to mediate ligand-enhanced transcription activation positively or negatively, for different steroid receptors. Taken together, our results indicate a potential role of PIAS3 as transcriptional modulator of TIF2-mediated signalling. |
