Scientific Data Images for Human PIAS2 Antibody

Detection of Human PIAS2 antibody by Western Blot.

Detection of Human PIAS2 by Western Blot.

Western blot shows lysates of MCF-7 human breast cancer cell line, HepG2 human hepatocellular carcinoma cell line, HeLa human cervical epithelial carcinoma cell line, and HEK293 human embryonic kidney cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human PIAS2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4768) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PIAS2 at approximately 63-70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PIAS2

PIAS2 (Protein inhibitor of activated STAT2; also DIP, MIZ1 and PIASx-beta) is a 45‑70 kDa member of the PIAS family of molecules. In primary cells and tissues it is expressed in T and NK cells, and in testis where it likely regulates spermatogenesis. However, it is widely expressed in cultured cell lines. PIAS2 is known to inhibit STAT4-mediated gene activation, and to interact with inactive ELK‑1, promoting its activation via HDAC2 dissociation and desumoylation. Human PIAS2 is 621 amino acids (aa) in length. It contains a SAP domain (aa 11‑45), a zinc-finger region (aa 331‑408), a SUMO-binding motif (aa 467‑472) and an NLS (aa 484‑492). There are multiple splice variants. PIAS2x-beta /ARIP3 shows a 22 aa substitution for aa 551‑621, while PIAS-NY shows a 12 aa substitution for aa 1‑8, followed by a truncation after Gly401. Two others show a four aa substitution for aa 504‑621, and an alternate start site at Met10. Over aa 1‑550, human PIAS2 shares 98% aa identity with mouse PIAS2.
