General annotation (Comments)

Function	Functions as an E3-type small ubiquitin-like modifier (SUMO) ligase, stabilizing the interaction between UBE2I and the substrate, and as a SUMO-tethering factor. 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 By similarity. The effects of this transcriptional coregulation, transactivation or silencing, may vary depending upon the biological context. Together with PRMT1, may repress STAT1 transcriptional activity, in the late phase of interferon gamma (IFN-gamma) signaling. 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. Ref.11
Pathway	Protein modification; protein sumoylation.
Subunit structure	Interacts with STAT1 By similarity. Interacts with NR2C1; the interaction promotes its sumoylation. Interacts with DDX21, CSRP2, AXIN1, JUN, SATB2, PLAG1, TP53 and STAT1 (dimer), following IFNA1-stimulation. Interacts with SP3 (preferentially when SUMO-modified). Interacts with KLF8; the interaction results in SUMO ligation and repression of KLF8 transcriptional activity and of its cell cycle progression into G1 phase By similarity. Interacts with CHUK/IKKA; this interaction induces PIAS1 phosphorylation. Interacts with PTK2/FAK1; the interaction promotes its sumoylation By similarity. Interacts with SUMO1, UBE2I, NCOA2 and AR. Interacts with NR2C1; the interaction promotes its sumoylation. Interacts with DDX5 By similarity. Interacts with PML (isoform PML-12) Ref.5 Ref.6 Ref.9 Ref.11
Subcellular location	Nucleus speckle By similarity. Nucleus › PML body. Note: Interaction with CSRP2 may induce a partial redistribution along the cytoskeleton By similarity. Ref.6 Ref.11
Tissue specificity	Expressed in kidney, heart, spleen, brain and cerebellum; weak expression, if any, in liver and lung. Ref.4
Developmental stage	Expressed as early as 7.6 dpc. Expression remains high through 15.5 dpc. Ref.4
Domain	The LXXLL motif is a transcriptional coregulator signature. The SP-RING-type domain is required for promoting EKLF sumoylation.
Post-translational modification	Sumoylated By similarity. Ref.6 Ref.7 Ref.8 Dimethylated by PRMT1 at Arg-303 in the late phase of interferon gamma (IFN-gamma) signaling, leading to preferential interaction with STAT1 and thus resulting in release of STAT1 from its target gene By similarity.
Sequence similarities	Belongs to the PIAS family. Contains 1 PINIT domain. Contains 1 SAP domain. Contains 1 SP-RING-type zinc finger.
