PIAS3 (protein inhibitor of activated STAT protein 3) is a 65-75 kDa member of the PIAS family of proteins. It is a ubiquitously expressed nuclear E3-type SUMO ligase that binds to, and inhibits, the gene activating activity of STAT3, MITF and the progesterone receptor. Human PIAS3 is 628 amino acids (aa) in length and contains a SAP domain (aa 11‑45) with an embedded transcriptional coregulator LxxLL motif, a STAT3 binding site (aa 82‑132), a PINIT motif required for nuclear retention (aa 241‑245), an SP-RING-type zinc finger domain (aa 303‑380) and a SUMO1-binding region (aa 450‑460). There is an alternate start site at Met10. Human PIAS3 is 97% aa identical to mouse and canine PIAS3 over both aa 1‑628 and 10‑628.

Scientific Data Images for Human PIAS3 Antibody
Detection of Human PIAS3 by Western Blot.
Western blot shows nuclear extracts of HepG2 human hepatocellular carcinoma cell line, HEK293 human embryonic kidney cell line, and MCF-7 human breast cancer cell line. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human PIAS3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5120) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for PIAS3 at approximately 65-75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human PIAS3 Antibody
