PIAS proteins act as transcriptional co-regulators with at least 60 different proteins in order to either activate or repress transcription. The transcription factors STAT, NF-κB, p73, and p53 are among the many proteins that PIAS interacts with. PIAS proteins have potential applications in cancer treatment and prevention. They may also play an important role in regulating immune system responses.
