The ZIC2 recombinant protein is derived from the ZIC2 gene, which encodes a member of the zinc finger-containing ZIC family of transcription factors. These proteins are evolutionarily conserved and play critical roles in embryonic development, particularly in neural patterning, neurogenesis, and left-right axis determination. ZIC2 contains a C2H2-type zinc finger domain near its N-terminus, enabling DNA binding and interaction with other regulatory proteins, while its C-terminal region mediates transcriptional activation or repression. Dysregulation of ZIC2 is linked to congenital disorders like holoprosencephaly (HPE) and neurodevelopmental conditions.
Recombinant ZIC2 protein is typically produced in vitro using expression systems (e.g., E. coli, mammalian cells) to study its molecular functions. It retains the native protein's structural and functional properties, allowing researchers to analyze DNA-binding specificity, protein-protein interactions, and downstream gene regulation. Purified ZIC2 recombinant protein often includes affinity tags (e.g., His-tag) for isolation and may undergo post-translational modifications when expressed in eukaryotic systems.
In research, ZIC2 recombinant protein is used to investigate mechanisms of neural crest cell differentiation, neural tube closure, and stem cell pluripotency maintenance. It also serves as a tool to model pathogenic mutations or evaluate ZIC2's role in signaling pathways like SHH (Sonic Hedgehog). Additionally, it aids in drug screening for therapies targeting ZIC2-associated disorders. The availability of recombinant ZIC2 has advanced studies on its dual role as a transcriptional activator and repressor, revealing context-dependent interactions with chromatin modifiers and developmental signaling cascades. Its utility extends to disease modeling, particularly in understanding how ZIC2 mutations disrupt embryonic patterning and contribute to congenital malformations.
