PIAS4

E3 SUMO-protein ligase PIAS4 is one of several is_associated_with::protein inhibitor of activated STAT (PIAS) proteins. It is also known as protein inhibitor of activated STAT protein gamma (PIASg or PIASy), and is an is_associated_with::enzyme that in humans is encoded by the PIAS4 is_associated_with::gene.

Interactions
PIAS4 has been shown to interact with is_associated_with::Mothers against decapentaplegic homolog 6, is_associated_with::Mothers against decapentaplegic homolog 7 and is_associated_with::Lymphoid enhancer-binding factor 1.
