Recombinant Mouse PIAS4 Protein，His

PIAS4 (Protein Inhibitor of Activated STAT4) is a member of the PIAS family of proteins, which are known to modulate various signaling pathways, particularly those involved in immune responses and cytokine signaling. Its primary function is to act as an E3 ubiquitin ligase that promotes the SUMOylation of specific target proteins, thereby regulating transcription and maintaining cellular homeostasis. Research has highlighted the role of PIAS4 in the modulation of signal transducer and activator of transcription (STAT) signaling pathways, particularly STAT4, which is critical for T-cell differentiation and the immune response against infections. Dysregulation of PIAS4 has been implicated in various diseases, including autoimmune disorders and cancers. Understanding the structure and function of PIAS4, as well as its interaction with other proteins and the molecular mechanisms underlying its activity, is essential for elucidating its biological roles. The development of recombinant PIAS4 proteins provides a valuable tool for studying its function and regulation in cellular systems, as well as for exploring potential therapeutic targets in immune-related diseases. Current research aims to clarify these aspects through biochemical analyses, structural studies, and in vivo models, contributing to a deeper understanding of PIAS4 and its potential implications in biomedicine.
