**Background of Recombinant Human ZNF42 Protein**
The recombinant human ZNF42 protein, also known as Zinc Finger Protein 42. belongs to the Krüppel-associated box (KRAB) domain-containing zinc finger protein family, which plays critical roles in transcriptional regulation and chromatin remodeling. Structurally, ZNF42 contains multiple Cys2His2 (C2H2) zinc finger motifs that facilitate sequence-specific DNA binding, enabling its interaction with target gene promoters or regulatory elements. The KRAB domain, located at the N-terminus, often mediates recruitment of co-repressor complexes, such as KAP1/TRIM28. to silence gene expression epigenetically via histone modification or DNA methylation.
ZNF42 is implicated in diverse biological processes, including stem cell pluripotency, cellular differentiation, and tumorigenesis. Studies suggest its involvement in maintaining embryonic stem cell identity by repressing differentiation-associated genes. Dysregulation of ZNF42 has been linked to cancers, where aberrant expression may promote oncogenic pathways or genomic instability. Additionally, its role in neurological development and immune regulation is under investigation.
Recombinant ZNF42 is produced using expression systems (e.g., *E. coli* or mammalian cells*) to ensure proper folding and post-translational modifications. It serves as a vital tool for studying DNA-protein interactions, epigenetic mechanisms, and disease pathways. Applications include in vitro binding assays, functional genomics, and screening for therapeutic agents targeting zinc finger protein-mediated disorders. Ongoing research aims to harness its regulatory potential for gene therapy or precision medicine strategies.
