Chimeric RNA isoforms generated by diverse mechanisms from two C-type lectins modulate innate immunity in arthropods

Proceedings of the National Academy of Sciences, Volume 122, Number 41, October 2025.
Chimeric RNA formation represents a critical mechanism for the expansion of protein functional diversity, but its role in invertebrate immune adaptation remains poorly characterized. Here we report that two C-type lectingens (MnLec2 and MnLec3) originating from distinct…
