A fatty acid-binding protein links lipid handling to chitin synthase-dependent cuticle formation and nanoscale organization
Background: The insect cuticle is a chitin-containing extracellular matrix whose formation requires precise coordination of chitin biosynthesis, fibril organization, and post-synthetic maturation. Although lipids are essential components of the cuticle, the molecular mechanisms linking lipid transport to chitin deposition remain poorly understood. Here we identify TcFabp8, a fatty acid-binding…
