PIAS3 encodes a member of the PIAS [protein inhibitor of activated STAT (signal transducer and activator of transcription)] family of transcriptional modulators. Protein inhibitor of activated STAT 3 functions as a SUMO (small ubiquitin-like modifier)-E3 ligase which catalyzes the covalent attachment of a SUMO protein to specific target substrates. It directly binds to several transcription factors and either blocks or enhances their activity. Alternatively spliced transcript variants of PIAS3 have been identified, but the full-length nature of some of these variants has not been determined蛋白别名为：PIAS3; E3 SUMO-protein ligase PIAS3; Protein inhibitor of activated STAT protein 3;基因ID为：10401；蛋白质ID:Q9Y6X2
