ZSCAN2 (Zinc Finger and SCAN Domain-Containing Protein 2) is a member of the SCAN family of transcription factors, characterized by a conserved SCAN domain involved in protein-protein interactions and C-terminal C2H2-type zinc finger motifs that bind DNA. Human ZSCAN2 is encoded by the *ZSCAN2* gene on chromosome 1p36.33 and is primarily expressed in embryonic stem cells (ESCs) and certain cancer cell lines. Research suggests it plays roles in maintaining pluripotency by regulating target genes associated with self-renewal and differentiation, though its precise mechanisms remain unclear. Studies indicate ZSCAN2 may act as a transcriptional repressor or activator, depending on cellular context, and interact with chromatin modifiers to modulate gene expression. Recombinant human ZSCAN2 protein (rZSCAN2), typically produced in *E. coli* or mammalian expression systems, retains DNA-binding activity and is used in vitro to study its interactions with DNA motifs, co-regulatory proteins, or epigenetic complexes. Functional studies employing rZSCAN2 have implicated it in cell cycle regulation, antiviral responses, and tumorigenesis, though further validation is needed. Its application in reprogramming somatic cells or enhancing stem cell-based therapies is an area of active exploration, leveraging its potential to influence pluripotency networks. However, tissue-specific roles and cross-species functional conservation of ZSCAN2 require deeper investigation to clarify its physiological relevance.
