    motifs/domains
  • a putative zinc finger binding motif
  • an LXXLL coregulator signature motif located within the N-terminal region requiremed for the interaction with RELA
  • a SAP (SAF-A/B,Acinus and PIAS) domain
  • a MIZ-type zinc finger
  • a conserved domain of 180 residues in PIAS proteins and its 'PINIT' motif as well as other conserved motifs (in the SAP box and in the RING domain), and this conserved proline, isoleucine, asparagine, isoleucine, threonine (PINIT) domain is thought to promote STAT3-PIAS3 interaction

    basic FUNCTION
  • a specific inhibitor of signal transducer and activator of transcription 3 (STAT3)
  • a key molecule in supressing the transcriptional activity of MITF and a role in mast cell and melanocyte development
  • modulating the ability of NCOA2 to mediate ligand-enhanced transcription activation positively or negatively, for different steroid receptors
  • may function as a modulator in suppressing the transcriptional activity of RELA
  • pias3-mediated SUMOylation of photoreceptor-specific transcription factors as a key mechanism of rod specification
  • acts as a dual-function transcriptional co-regulator to simultaneously coordinate expression of the Opn1mw and Opn1sw genes
  • Pias3-dependent SUMOylation has a role in both developing rods and cones and in regulating cone photoreceptor subtype specification
  • is a novel regulator of ERBB4 receptor tyrosine kinase, controlling its nuclear sequestration and function
  • PIAS3 primes ATR for checkpoint activation by sustaining its basal kinase activity, revealing a new function of the PIAS family in DNA damage signaling
  • functions as a positive regulator of HIF1A-mediated transcription by increasing its protein stability
  • is necessary for dorso-ventral patterning and visual response of retinal cones but is not required for rod photoreceptor differentiation
  • is implicated in guiding specification of rod and cone photoreceptors through post-translational modification of key retinal transcription factors
  • CELLULAR PROCESS cell life, differentiation
    nucleotide, transcription, regulation

  • mineralocorticoid receptor, MR
  • TATA-binding protein, TBP
  • SERPINE1 mRNA binding protein 1, SERBP1
  • tripartite motif-containing 32, TRIM32
  • interaction between ZMIZ2 and PIAS proteins with higher preference for PIAS3
  • is a novel interaction partner of ERBB4 soluble intracellular domain (ICD)
  • PIAS3-mediated SUMOylation of endogenous RELA was induced by NFKB1 activation thus forming a negative regulatory loop (
  • TP;PIAS3 interaction through the 1-52 amino acid region of TP53, reduces TP53&
  • 8209;MDM2 complex formation, which not only increases the half-life of TP53, but also its transactivation of target genes
  • PIAS3 is a transcriptional corepressor of KLF1 for at least a subset of its target genes during erythropoiesis
  • is the only member of the PIAS family that is indispensable for ATR activation
  • PIAS3 physically associated with HIF1A, and PIAS3 enhances the transcriptional activity of HIF1A by increasing its protein stability
  • is a negative regulator of STAT3 activity

    TypeGene ModificationChromosome rearrangementProtein expressionProtein Function
    constitutional     --low  
    significantly lower, in women with endometriosis compared to women without endometriosis, and attenuation of PIAS3 causes likely aberrant activation of STAT3 in endometriosis, leading to inflammatory changes that may impair fertility or cause pain
    tumoral     --low  
    is more negatively correlated with STAT3 activation in the stepwise progress of astrocytomas and would indicate an unfavorable outcome
    tumoral     --low  
    in malignant mesothelioma is associated with increased STAT3 activation and poor patient survival
