Unbiased phylogenetic profiling across the complete human methyltransferase repertoire reveals extensive coevolution with many cytoskeletal components, including an experimentally validated NSD3–α-tubulin association.
- Why it matters: Cytoskeletal protein methylation is widespread, but the responsible enzymes and how they relate evolutionarily to canonical chromatin methylation substrates remain unclear.
- What they did: They performed phylogenetic profiling across all human methyltransferases, used unbiased clustering and Evolutionary Trace analysis to map conserved coevolution and constrained residues, then experimentally validated a methyltransferase–cytoskeleton link.
- The result: The methyltransferase–cytoskeleton relationships include both ancient and later eukaryotic lineage programs, and evolutionary signatures identified NSD3 as associated with α-tubulin.
