**Background of Recombinant Human ZIC3 Protein**
The recombinant human ZIC3 protein is a engineered version of the zinc finger protein ZIC3. encoded by the *ZIC3* gene located on the X chromosome (Xq26.3). As a member of the ZIC family, ZIC3 contains five C2H2-type zinc finger domains that mediate DNA or RNA binding, playing critical roles in embryonic development, particularly in establishing left-right asymmetry, neural tube closure, and neural crest cell differentiation.
Mutations in *ZIC3* are linked to X-linked heterotaxy syndrome, a disorder characterized by visceral organ malposition and congenital heart defects. Recombinant ZIC3 is typically produced in heterologous systems (e.g., *E. coli* or mammalian cell lines) to study its molecular functions. The protein interacts with signaling pathways like Wnt and Nodal, modulating transcription of target genes such as *NODAL* and *LEFTY2*. It also exhibits nuclear-cytoplasmic shuttling, regulated by post-translational modifications.
Beyond developmental biology, ZIC3 is implicated in cancer progression, where its overexpression correlates with tumor invasiveness and stemness. Recombinant ZIC3 serves as a tool for structural studies, functional assays, and therapeutic exploration, bridging gaps in understanding genetic disorders and developmental mechanisms.
