Zinc finger protein 622 (ZNF622) is a member of the C2H2-type zinc finger protein family, characterized by conserved zinc-binding motifs that facilitate interactions with nucleic acids or proteins. Predominantly localized in the nucleus, ZNF622 is implicated in transcriptional regulation, RNA processing, and post-translational modifications. Studies suggest it may act as a transcriptional repressor or co-regulator, potentially influencing cellular processes such as proliferation, differentiation, or apoptosis. Structurally, ZNF622 contains multiple tandem zinc finger domains, a nuclear localization signal, and regions associated with protein-protein interactions, including a conserved C-terminal motif.
Emerging research links ZNF622 to cancer biology. It is reportedly overexpressed in certain malignancies, including hepatocellular carcinoma and breast cancer, where it may promote tumor progression by modulating oncogenic pathways or epigenetic regulators. For instance, ZNF622 interacts with RBM39. a splicing factor involved in cancer cell survival, hinting at its role in RNA metabolism. Recombinant human ZNF622 protein has been engineered for in vitro studies, enabling functional characterization, antibody production, and screening for small-molecule inhibitors. Current challenges include clarifying its precise molecular targets, signaling networks, and therapeutic relevance. While its physiological roles remain incompletely understood, ZNF622's nuclear shuttling activity and disease associations highlight its potential as a biomarker or intervention target in precision medicine. Further studies are needed to unravel its context-dependent functions and regulatory mechanisms across tissues.
