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. The effects of this transcriptional coregulation, transactivation or silencing may vary depending upon the biological context and PIAS2 isoform studied. However, it seems to be mostly involved in gene silencing. Binds to sumoylated ELK1 and enhances its transcriptional activity by preventing recruitment of HDAC2 by ELK1, thus reversing SUMO-mediated repression of ELK1 transactivation activity. Isoform PIASx-beta, but not isoform PIASx-alpha, promotes MDM2 sumoylation. Isoform PIASx-alpha promotes PARK7 sumoylation. Isoform PIASx-beta promotes NCOA2 sumoylation more efficiently than isoform PIASx-alpha By similarity.

Pathway

Protein modification; protein sumoylation.

Subunit structure

Binds SUMO1 and UBE2I. Interacts with AXIN1, JUN, MDM2, PARK7, TP53 and TP73 isoform alpha, but not TP73 isoform beta. Interacts with STAT4 following IL12 and IFN-alpha stimulation of T-cells. Interacts also with GTF2I, GTF2IRD1, IKFZ1, DAB2 and MSX2, as well as with several steroid receptors, including ESR1, ESR2, NR3C1, PGR, AR, and with NCOA2. Sumoylation of a target protein seems to enhance the interaction. Binds to sumoylated ELK1. Interacts with PLAG1 By similarity. Binds DNA, such as CDKN1A promoter, in a sequence-specific manner. 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.

Subcellular location

Nucleus speckle. NucleusPML body. Note: Colocalizes at least partially with promyelocytic leukemia nuclear bodies (PML NBs). Ref.6 Ref.7

Domain

The LXXLL motif is a transcriptional coregulator signature.

Post-translational modification

Sumoylated. Ref.7

Sequence similarities

Belongs to the PIAS family.

Contains 1 PINIT domain.

Contains 1 SAP domain.

Contains 1 SP-RING-type zinc finger.

Sequence caution

The sequence AAB96678.1 differs from that shown. Reason: Erroneous initiation.

The sequence BAB29594.1 differs from that shown. Reason: Frameshift at position 34.
