Technical Data
PIAS1 (E3 SUMO-protein Ligase PIAS1, Protein Inhibitor of Activated STAT Protein 1, Gu Binding Protein, GBP, RNA Helicase II Binding Protein, DEAD/H Box-binding Protein 1, DDXBP1, MGC141878, MGC141879)
PIAS1 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. This protein plays a crucial role in transcriptional coregulation of various cellular pathways, including the STAT pathway, the p53 pathway and the steroid hormone signaling pathway. It functions in testis as a nuclear receptor transcriptional coregulator and may have a role in androgen receptor initiation and maintenance of spermatogenesis. The effects of transcriptional coregulation, transactivation or silencing, may vary depending upon the biological context.

Suitable for use in Western Blot. Other applications not tested.
