Here, we identify MrNIS1, an effector from the insect-pathogenic fungus\n                    <jats:italic>Metarhizium robertsii<\/jats:italic>\n                    whose stability and secretion are governed by K24 acetylation through physical association with the acetyltransferase MrKAT1 and the deacetylase MrSIR2. Once inside the insect, MrNIS1 acts as a dual-targeting effector to disrupt distinct physiological pathways. It binds the serine protease SPS to block prophenoloxidase activation, thereby suppressing melanization-based immunity. MrNIS1 interacts with the evolutionarily conserved cholesterol transporter ERP, disrupting ecdysteroid biosynthesis and leading to impaired larval growth and cuticle synthesis. This MrNIS1-ERP interaction is functionally conserved across Lepidoptera, Coleoptera, and Diptera. Furthermore, heterologous expression in\n                    <jats:italic>Beauveria bassiana<\/jats:italic>\n                    demonstrates that the KAT1\/SIR2 regulatory system is conserved across fungal species, where MrNIS1 acts as a portable virulence module to significantly enhance pathogen efficacy. Our findings reveal that lysine acetylation serves as a molecular switch that preserves effector competence during cross-kingdom transit, enabling the simultaneous targeting of multiple host physiological processes. These results elucidate a conserved strategy of fungal pathogenesis and identify potential targets for the improvement of microbial biocontrol agents.\n
