Recombinant human ZNF341 protein is a engineered form of the zinc finger protein 341. a transcription factor belonging to the Krüppel-associated box (KRAB) domain-containing zinc finger protein family. ZNF341 is encoded by the *ZNF341* gene and plays a critical role in regulating gene expression by binding to specific DNA sequences via its C2H2-type zinc finger domains. It is particularly notable for its interaction with STAT3 (signal transducer and activator of transcription 3), a key signaling molecule involved in immune regulation, cell growth, and differentiation. ZNF341 facilitates STAT3's nuclear translocation and transcriptional activity, thereby modulating immune responses and cellular homeostasis.
The recombinant protein is typically produced in vitro using expression systems like mammalian cells or *E. coli*, enabling studies on its structural and functional properties. Researchers utilize recombinant ZNF341 to investigate its role in immune disorders, such as autosomal dominant STAT3-deficient hyper-IgE syndrome (AD-STAT3 deficiency), where mutations in *ZNF341* impair STAT3 signaling, leading to immune dysregulation, recurrent infections, and eczema. This protein is also a tool for exploring therapeutic strategies targeting STAT3 pathways in cancers or autoimmune diseases. Recent studies highlight its potential as a biomarker or therapeutic target in conditions linked to dysregulated STAT3 activity. Understanding ZNF341's mechanisms offers insights into transcriptional regulation and disease pathogenesis.
