ZNF768 is a zinc finger transcription factor that binds to mammalian-wide interspersed repeat (MIR) sequences at the consensus motif 5'-GCTGTGTG-[N20]-CCTCTCTG-3' in euchromatin and gene promoter regions 1. The protein contains an N-terminal heptad repeat array structurally related to RNA polymerase II's C-terminal domain, suggesting involvement in transcriptional regulation 1. ZNF768 is essential for cell homeostasis and plays a critical role in regulating cell fate decisions by linking oncogenic RAS signaling to cellular senescence control 2. Upon RAS activation, ZNF768 is phosphorylated and destabilized; depletion of ZNF768 impairs proliferation and induces senescence through modulation of cell cycle effectors and p53 targets 2. Conversely, ZNF768 overexpression promotes RAS-induced senescence bypass by repressing p53 phosphorylation and activity, facilitating malignant transformation 2. Clinically, ZNF768 is frequently amplified and overexpressed in tumors 2. ZNF768 autoantibodies have emerged as immunotherapy biomarkers; elevated ZNF768-specific autoantibodies associate with increased immune-related adverse event risk in non-small-cell lung cancer patients receiving immune checkpoint inhibitor treatment 3, and demonstrate enhanced immunogenicity in colorectal cancer detection 4.
