Abstract: Zinc finger(ZF) structure is a kind of common protein structure widely existing in animals, plants, microorganisms including many viruses. The characteristic group of amino acid residues in the peptide chain combines with Zn2+, thus forming a very short peptide space configuration which can self fold into "finger" shape. Zinc-finger proteins (ZNF) are proteins with zinc finger structure. It has been found that some viruses can encode zinc finger proteins, which can affect virus replication, packaging and release of mature virus particles, regulate and activate virus transcription and cleavage infection, and assist virus in innate immune escape. In this paper, the research progress of the role of ZNF in the process of virus infection is reviewed, which provides a reference for the further study of ZNF and the development of its targeting antiviral drugs.

Key words: zinc finger protein, zinc fingers, viral infection
