Identification of candidate mechanosensory transduction channels in the aquatic insect Protohermes xanthodes (Megaloptera: Corydalidae) by transcriptome analysis.

ABSTRACT: Protohermes species are among the top aquatic predators in benthic invertebrate communities. Their ability to perceive mechanical stimuli may be functional in mediating responses to freshwater environmental cues. In this study, we performed a transcriptome analysis of the antennae, maxillae, and labium of Protohermes xanthodes Navás larvae (Megaloptera: Corydalidae), identifying 2 transmembrane protein genes (PxanPiezo and PxanNompC), which are phylogenetically related to mechanosensory transduction channels in other insects. PxanPiezo is a large transmembrane protein featuring 38 transmembrane helices that mediate its association with the cytoplasm. PxanNompC is another transmembrane protein containing an extensive intracellular ankyrin repeat domain, a structural feature that enables pot
