ZNF473. also known as Krüppel-associated box (KRAB)-containing zinc finger protein 473. is a member of the zinc finger protein family characterized by C2H2-type zinc finger motifs. These motifs enable sequence-specific DNA or RNA binding, facilitating roles in transcriptional regulation and chromatin remodeling. ZNF473 contains multiple tandem zinc finger domains and a KRAB domain, which often mediates interactions with co-repressor complexes like heterochromatin protein 1 (HP1) or histone-modifying enzymes, contributing to gene silencing and epigenetic regulation.
Studies suggest ZNF473 plays a critical role in maintaining genome stability and cellular differentiation. It is implicated in DNA damage response pathways and may interact with polycomb group proteins to regulate stem cell pluripotency. Additionally, ZNF473 has been linked to X chromosome inactivation, potentially through its association with non-coding RNAs. Dysregulation of ZNF473 is observed in cancers, including leukemia and solid tumors, where altered expression correlates with disease progression or therapy resistance.
Recombinant human ZNF473 protein, produced via heterologous expression systems like *E. coli* or mammalian cells, retains functional domains for biochemical studies. It is utilized to investigate DNA-protein interactions, screen small molecule inhibitors, or explore its role in chromatin dynamics. Its structural and functional conservation across vertebrates highlights its biological significance, making it a target for therapeutic and diagnostic research in oncology and developmental disorders.
