Plays a crucial role as a transcriptional coregulation in various cellular pathways, including the STAT pathway, the p53 pathway and the steroid hormone signaling pathway. In vitro, binds A\/T-rich DNA. The effects of this transcriptional coregulation, transactivation or silencing, may vary depending upon the biological context. Sumoylates PML (at'Lys-65' and 'Lys-160') and PML-RAR and promotes their ubiquitin-mediated degradation. PIAS1-mediated sumoylation of PML promotes its interaction with CSNK2A1\/CK2 which in turn promotes PML phosphorylation and degradation. Enhances the sumoylation of MTA1 and may participate in its paralog-selective sumoylation. Plays a dynamic role in adipogenesis by promoting the SUMOylation and degradation of CEBPB.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExpression and localization notes:\u003c\/strong\u003e cellular localization: Nucleus speckle.

It is mapped to 15q23. This gene encodes a member of the protein inhibitor of activated STAT (PIAS) family. PIAS proteins function as SUMO E3 ligases and play important roles in many cellular processes by mediating the sumoylation of target proteins. This protein plays a central role as a transcriptional coregulator of numerous cellular pathways includign the STAT1 and nuclear factor kappaB pathways. Alternate splicing results in multiple transcript variants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Nucleus speckle.
