Applications
Western Blot (Transfected lysate)
Western blot analysis of PIAS1 (arrow) using PIAS1 polyclonal antibody (Cat # PAB1851). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the PIAS1 gene (Lane 2) (Origene Technologies).Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
Formalin-fixed and paraffin-embedded human hepatocellular carcinoma tissue reacted with PIAS1 polyclonal antibody (Cat # PAB1851), 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. -

HyperlinkGene Summary
This gene encodes a member of the mammalian PIAS [protein inhibitor of activated STAT-1 (signal transducer and activator of transcription-1)] family. This member contains a putative zinc-binding motif and a highly acidic region. It inhibits STAT1-mediated gene activation and the DNA binding activity, binds to Gu protein/RNA helicase II/DEAD box polypeptide 21, and interacts with androgen receptor (AR). It functions in testis as a nuclear receptor transcriptional coregulator and may have a role in AR initiation and maintenance of spermatogenesis. [provided by RefSeq
