Q8N2W9 PIAS4_HUMAN:

Highly expressed in testis and, at lower levels, in spleen, prostate, ovary, colon and peripheral blood leukocytes.

Description:
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, the Wnt pathway and the steroid hormone signaling pathway.

Research Backgrounds

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/TP53 pathway, the Wnt pathway and the steroid hormone signaling pathway. Involved in gene silencing. Mediates sumoylation of CEBPA, PARK7, HERC2, MYB, TCF4 and RNF168. In Wnt signaling, represses LEF1 and enhances TCF4 transcriptional activities through promoting their sumoylations. Enhances the sumoylation of MTA1 and may participate in its paralog-selective sumoylation.

PTMs:

Sumoylated. Lys-35 is the main site of sumoylation. Sumoylation is required for TCF4 sumoylation and transcriptional activation. Represses LEF1 transcriptional activity. SUMO1 is the preferred conjugate.

Subcellular Location:

Nucleus>PML body.
Note: Colocalizes with SUMO1 and TCF7L2/TCF4 and LEF1 in a subset of PML (promyelocytic leukemia) nuclear bodies.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Highly expressed in testis and, at lower levels, in spleen, prostate, ovary, colon and peripheral blood leukocytes.

Subunit Structure:

Interacts with AR, AXIN1, GATA2, LEF1, TP53 and STAT1 (IFNG-induced). Binds to AT-rich DNA sequences, known as matrix or scaffold attachment regions (MARs/SARs) (By similarity). Interacts with TICAM1. Interacts with KLF8; the interaction results in SUMO ligation and repression of KLF8 transcriptional activity and of its cell cycle progression into G(1) phase. Interacts with MTA1.

Family&Domains:

The LXXLL motif is a coregulator signature that is essential for transcriptional corepression.

Belongs to the PIAS family.

The data were analyzed by Student's t-test. (B) Efficiency of UBC9 knockdown was analyzed by western blotting and was semi-quantified using densitometry. The data were analyzed by one-way ANOVA and Tukey post hoc test. (C and D) Co-IP suggested that the SUMOylation of STAT1 was enhanced under high-glucose conditions. The data were analyzed by one-way ANOVA and Tukey post hoc test. (E) Binding of STAT1 and PIASs was analyzed. Results suggested that PIAS4 mediated the upregulation of STAT1 SUMOylation. The data were analyzed by Student's t-test. (F) Efficiency of PIAS4 knockdown was analyzed by western blotting and was semi-quantified using densitometry. The data were analyzed by one-way ANOVA and LSD post hoc test. The effects of PIAS4 siRNA transfection on STAT1 SUMOylation (G) were analyzed by co-IP and (H) were semi-quantified using densitometry. The results suggested that PIAS4 knockdown inhibited STAT1 SUMOylation. The data were analyzed by one-way ANOVA and Tukey post hoc test. IP:STAT1 means the cell lysate was incubated with STAT1 antibody. Input was used as a positive control to detect the presence of target proteins. n=3. *P
