背景信息

ZNF81. a member of the zinc finger protein (ZFP) family, is a transcription factor characterized by conserved Cys2/His2-type zinc finger motifs. These motifs enable sequence-specific DNA binding, facilitating its role in transcriptional regulation. Located on the X chromosome, ZNF81 is ubiquitously expressed, with notable activity in brain, testes, and immune tissues. It shares structural homology with other KRAB-ZFPs, containing a Krüppel-associated box (KRAB) domain implicated in protein-protein interactions and transcriptional repression. Dysregulation of ZNF81 has been linked to neurodevelopmental disorders, including X-linked intellectual disability and autism spectrum disorders, suggesting its critical role in neural differentiation and synaptic function.

Recombinant human ZNF81 protein is typically produced using heterologous expression systems (e.g., E. coli, mammalian cells) for functional studies. Its engineered versions often include purification tags (His, GST) and optimized solubility features. Current research focuses on characterizing its DNA-binding specificity, interactome mapping with chromatin modifiers, and elucidating mechanisms in gene silencing. Recombinant ZNF81 serves as a vital tool for in vitro assays, including electrophoretic mobility shift assays (EMSAs) and high-throughput screening for potential therapeutic modulators. Structural studies using recombinant protein aim to inform drug design targeting ZNF81-associated pathologies while minimizing off-target effects on related ZFPs.
