Zinc finger protein 239 (ZNF239), also known as ZFP239 or ZKSCAN4. is a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein (ZFP) family. These proteins are characterized by tandem Cys2His2 (C2H2)-type zinc finger motifs that mediate sequence-specific DNA binding, coupled with a KRAB domain at the N-terminus that typically recruits transcriptional corepressors to regulate gene expression. ZNF239 is encoded by the *ZNF239* gene located on human chromosome 7q22.1.
As a transcription factor, ZNF239 has been implicated in modulating cellular processes such as proliferation, differentiation, and apoptosis. It binds to GC-rich promoter regions of target genes, functioning as a transcriptional repressor. Studies suggest its involvement in tumorigenesis, with aberrant expression observed in cancers like neuroblastoma and glioma. For instance, ZNF239 may interact with p53 signaling pathways or regulate oncogenic kinases, though its precise mechanistic roles remain under investigation.
Recombinant human ZNF239 protein is typically produced using bacterial or mammalian expression systems to enable functional studies. This engineered protein retains DNA-binding activity and is used to explore interactions with regulatory DNA elements, protein partners, or epigenetic modifiers. Its recombinant form also serves as a tool for developing disease models or screening potential inhibitors targeting zinc finger-mediated transcriptional regulation. Further research is needed to clarify its tissue-specific functions and therapeutic relevance in human diseases.
