"PIAS3 blocked the DNA- binding activity of Stat3 and inhibited Stat3-mediated gene activation. Although Stat1 is also phosphorylated in response to IL-6, PIAS3 did not interact with Stat1 or affect its DNA-binding or transcriptional activity. The results indicate that PIAS3 is a specific inhibitor of Stat3."
"Specific inhibition of stat3 signal transduction by pias3stat3 mediated signaling pathways can be inhibited by pias3 (protein inhibitor of activated stat3), which was recently found to regulate protein stability and function by its sumo (small-ubiquitin like modifiers) ligase activity in promoting sumoylation of important nuclear proteins."
