Summary |
The zinc finger antiviral protein (ZAP) depletes non-self RNAs through recognition of their elevated CpG dinucleotide content. CpG dinucleotides are sparse in most endogenous mammalian mRNAs, but a subset might potentially be modulated by ZAP. While CpG frequency alone is insufficient to predict ZAP-regulation, we developed an algorithm using experimentally determined compositional features to predict which endogenous mRNAs may be ZAP-regulated. Using ZAP-knockout mice, we demonstrate that levels of many host mRNAs that are algorithmically predicted ZAP targets are indeed increased when ZAP is absent. ZAP is interferon-inducibel and we also identify genes that are downregulated by ZAP during an innate immune response. Many ZAP-regulated gene products are extracellular matrix or of nucleosome components, whose ZAP mediated control is conserved in human cells. Overall, we provide a new tool for the prediction of ZAP target genes and reveal host mRNAs that are ZAP-regulated.

Overall design |
The goal of the experiment was to analyze RNA sequences bound by the Zinc Finger Antiviral Protein (ZAP). ZAP:RNA complexes were extracted and purified from MT4 cells, reversed transcribed and analysed by NGS. Two biological replicates are included.
