Zinc finger protein 304 (ZNF304) is a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein family, which plays a role in transcriptional regulation and chromatin remodeling. Encoded by the ZNF304 gene in humans, this protein features multiple C2H2-type zinc finger motifs that enable sequence-specific DNA binding, typically targeting GC-rich promoter regions. Its KRAB domain facilitates interactions with co-repressors like TRIM28/KAP1. recruiting chromatin-modifying complexes to mediate gene silencing through histone deacetylation or methylation.
ZNF304 has been implicated in epigenetic regulation, particularly in cancer. Studies suggest it acts as an oncogene in certain contexts, promoting tumor progression by repressing tumor suppressor genes (e.g., CDKN2A/p16) via Polycomb repressive complex 2 (PRC2)-dependent H3K27me3 deposition. Conversely, it may exhibit tumor-suppressive roles in other malignancies, highlighting context-dependent functionality. It also participates in maintaining stem cell pluripotency and cellular differentiation, though mechanisms remain incompletely understood.
Structurally, recombinant human ZNF304 is often expressed in vitro (e.g., E. coli or mammalian systems) for functional studies, preserving its DNA-binding and protein interaction domains. Dysregulation of ZNF304 correlates with poor prognosis in cancers such as colorectal and ovarian cancer. Current research focuses on elucidating its target genes, signaling cross-talk, and potential as a therapeutic biomarker. Further investigations are needed to resolve contradictions in its dual roles and tissue-specific regulatory networks.
