ZSCAN20 recombinant protein is a engineered version of the human ZSCAN20 protein, a member of the zinc finger and SCAN domain-containing (ZSCAN) transcription factor family. This protein is characterized by its conserved C-terminal C2H2-type zinc finger motifs, which mediate sequence-specific DNA binding, and an N-terminal SCAN domain that facilitates protein-protein interactions. The ZSCAN20 gene is located on chromosome 1q25.3 and encodes a nuclear protein implicated in transcriptional regulation, though its precise biological functions remain under active investigation.
Recombinant ZSCAN20 is typically produced in heterologous expression systems (e.g., E. coli or mammalian cells) with purification tags (e.g., His-tag) to enable standardized production. This engineered approach allows researchers to study ZSCAN20's molecular interactions, DNA-binding specificity, and regulatory roles in cellular processes. Emerging evidence suggests potential involvement in cell differentiation, tumorigenesis, and neurological pathways, though mechanistic details are not fully established. Some studies propose interactions with chromatin-modifying complexes and cell cycle regulators.
The availability of recombinant ZSCAN20 protein has advanced structural studies (e.g., crystallography of DNA-binding domains) and functional assays (e.g., electrophoretic mobility shift assays). It also serves as an antigen for antibody development and a tool for identifying target gene promoters. Current research focuses on elucidating its role in cancer progression (particularly in gliomas and leukemias) and neurodevelopmental disorders, with some reports linking ZSCAN20 dysregulation to abnormal neural crest cell migration. However, comprehensive pathway mapping and validation in disease models remain areas of active exploration.
