A chymotrypsin-like serine protease interacts with the chitin synthase from the midgut of the tobacco hornworm
Journal of Experimental Biology
The chitin portion of the peritrophic matrix in the midgut of the tobacco hornworm, Manduca sexta, is produced by chitin synthase 2 (CHS2), a transmembrane family II glycosyltransferase, located at the apical tips of brush border microvilli. To look for proteins that potentially interact with CHS2, we performed yeast twohybrid screening, identifying a novel chymotrypsin-like protease (CTLP1) that binds to the extracellular carboxyterminal domain of CHS2. The occurrence of this interaction indoi:10.1242/jeb.008334 pmid:17921165 fatcat:juvkrdqcqfh6vmf4yprd6cbefa
