Technical Data
P4086-01A
PIAS1, CT 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)
Description:
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.
