Our recent study on the functional analysis of the Knickkopf protein from T. castaneum (TcKnk), indicated a novel role for this protein in protection of chitin from degradation by chitinases. Knk is also required for the laminar organization of chiti

Molting, or the replacement of the old exoskeleton with a new cuticle, is a complex developmental process that all insects must undergo to allow unhindered growth and development. Prior to each molt, the developing new cuticle must resist the actions

Formation of rigid, non-flight forewings (elytra) of a beetle requires two major cuticular proteins.

Insect cuticle is composed primarily of chitin and structural proteins. To study the function of structural cuticular proteins, we focused on the proteins present in elytra (modified forewings that become highly sclerotized and pigmented covers for t

The functional characterization of an entire class of 17 genes from the red flour beetle, Tribolium castaneum, which encode two families of Cuticular Proteins Analogous to Peritrophins (CPAPs) has been carried out. CPAP genes in T. castaneum are expr

Chitin, a homopolymer of β-1-4-linked N-acetylglucosamine synthesized by chitin synthase A (Chs-A), is organized in the procuticle of the postembryonic cuticle or exoskeleton, which is composed of laminae stacked parallel to the cell surface to give

Several benzoylphenyl urea-derived insecticides such as diflubenzuron (DFB, Dimilin®) are in wide use to control various insect pests. Although this class of compounds is known to disrupt molting and to affect chitin content, their precise mode of a

RNA interference or RNAi has been observed in eukaryotes and plays a critical role not only in messenger RNA degradation but also in fine-tuning of gene activation, transcription and translation. In insects, double-stranded RNA (dsRNA)-mediated gene

The insect cuticle is a composite biomaterial made up primarily of chitin and proteins. The physical properties of the cuticle can vary greatly from hard and rigid to soft and flexible. Understanding how different cuticle types are assembled can aid

During each molting cycle of insect development, synthesis of new cuticle occurs concurrently with the partial degradation of the overlying old exoskeleton. Protection of the newly synthesized cuticle from molting fluid enzymes has long been attribut

A bioinformatics search of the genome of the red flour beetle, Tribolium castaneum, resulted in the identification of two genes encoding proteins closely related to UDP-N-acetylglucosamine pyrophosphorylases (UAPs), which provide the activated precur
