ZIC4 recombinant protein is derived from the ZIC4 gene, which encodes a member of the ZIC family of zinc finger transcription factors. These proteins are characterized by a C2H2-type zinc finger domain and play critical roles in embryonic development, particularly in neural and cerebellar development. ZIC4. located on chromosome 3q24-q25 in humans, shares structural homology with other ZIC proteins, featuring conserved N-terminal and C-terminal domains that mediate DNA binding and protein-protein interactions. Dysregulation of ZIC4 has been linked to developmental disorders and cancers, including medulloblastoma and ovarian cancer, highlighting its importance in cellular differentiation and tissue homeostasis.
Recombinant ZIC4 protein is typically produced using expression systems like *E. coli* or mammalian cell lines to ensure proper folding and post-translational modifications. The protein is purified via affinity chromatography, often tagged with His or GST for detection and isolation. Its recombinant form enables functional studies, such as investigating its role in transcriptional regulation, epigenetic modulation, or signaling pathways like Wnt and Shh. Researchers utilize ZIC4 recombinant protein in *in vitro* assays, antibody development, and disease modeling to explore its interactions with DNA, histones, or partner proteins (e.g., GLI proteins).
Applications extend to therapeutic research, as ZIC4's involvement in stem cell pluripotency and tumorigenesis makes it a potential biomarker or drug target. Studies also leverage recombinant ZIC4 to dissect its contribution to congenital defects like Dandy-Walker malformation, offering insights into neurodevelopmental mechanisms. Its high purity and activity ensure reproducibility in experiments, bridging molecular biology with translational medicine.
