Article Title: DTX3L–PARP9 co-evolve as a single adaptive unit linking ubiquitination and ADP-ribosylation in antiviral immunity

doi: 10.64898/2026.04.23.720386

Figure Lengend Snippet: a) Domain architecture of Deltex family proteins, PARP9, and PARP14. Canonical domains are mapped along each protein using domain boundaries defined in InterPro, showing common and differing features between proteins from the same families. b) Phylogenetic representation of gene presence and absence across 21 metazoan classes. Filled cells indicate the presence of an ortholog, while empty cells denote absence. Deltex family proteins are shown in red (lighter red for inferred ancestral Deltex proteins) and PARP proteins in blue. Numbers on the right represent the number of species with the represented profile of presence and absence over the total number of species analyzed in the class. c) Maximum-likelihood phylogeny of the Deltex family reconstructed from full-length protein sequences. Major clades corresponding to DTX1–4 and DTX3L are labeled, with nodes support (bootstrap values) indicated by circles when > 0.7. d) Predicted domain architectures of DTX3L orthologs across representative metazoan species, illustrating conserved features and lineage-specific differences, and shared domains with PARP14. e) Graphical representation of the synteny of the canonical DTX3L locus across representative metazoan species and, the alternate PARP9-associated locus, showing the emergence of a conserved DTX3L-PARP9 locus following the diversification of dipnoi (lungfishes). f) Correlation between transcriptional expression (z) of DTX3L and PARP9 and their intergenic distance (Log10 genomic distance +1). Analysis was performed for different species ( Rattus norvegicus, Mus musculus, Homo sapiens, Macaca mulatta, Gallus gallus, Canis lupus and Felis catus ) show distinct intergenic distance, using available co-expression data from COXPRESdb. Significance of the slope was tested with Spearman test (ρ = −0.8, p-value = 0.029).
