The negative pathway regulator SU(VAR)2-10 physically interacts with the phosphorylated STAT92E dimer and prevents it from binding to it's pathway target genes and so inhibiting transcription.

SU(VAR)2-10 is a PIAS protein (protein inhibitors of activated STAT) and is also referred to as ZIMP protein.

In vertebrates, PIAS proteins control the duration of JAK/STAT signalling by targeting active STAT for degradation by SUMOlation.
