Reasoning linking viral HGT, gene structure, and venom-related function in tick capsid-like proteins

InferenceChain·arcadia

This chain explains how horizontal gene transfer (HGT) identified capsid and nucleocapsid genes of viral origin in tick genomes, demonstrates their eukaryotic integration based on introns and large contigs, and links salivary gland expression to potential venom function. It also shows that structure-based searches (Foldseek) confirm these genes as homologous to viral capsids and that similar proteins are found across parasitic and venomous animals.
