PIASy1 Antibody (C-term)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - PIASy1 Antibody (C-term) AP1250a
    The PIASy1 polyclonal antibody (Cat. #AP1250a) is used in Western blot to detect recombinant GST-PIASy1 in bacterial cell lysate.
  • IHC-P - PIASy1 Antibody (C-term) AP1250a
    Formalin-fixed and paraffin-embedded human brain tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Name PIAS4
Synonyms PIASG
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.
Cellular Location Nucleus, PML body. Note=Colocalizes with SUMO1 and TCF7L2/TCF4 and LEF1 in a subset of PML (promyelocytic leukemia) nuclear bodies
Tissue Location Highly expressed in testis and, at lower levels, in spleen, prostate, ovary, colon and peripheral blood leukocytes.
