Patent number: 7939647Abstract: An objective of the present invention is to provide polynucleotides encoding insect desiccation resistance proteins, and uses thereof. cDNA libraries were produced from Polypedilum vanderplanki larvae in a desiccated state, a P. vanderplanki EST database was constructed, and genes encoding LEA proteins were isolated. This resulted in the successful isolation of three types of novel gene encoding LEA-like proteins. When secondary structure predictions and motif searches were performed on the proteins deduced from each of the genes, all three proteins had ?-helix-rich structures and LEA_4 motifs, which are characteristic of LEA proteins. Moreover, the recombinant proteins synthesized from these genes were heat soluble even when boiling, so that these proteins have hydrophilic properties as high as plant LEA proteins. Therefore, the three isolated genes were found to be novel P. vanderplanki-derived LEA genes.Type: GrantFiled: November 21, 2008Date of Patent: May 10, 2011Assignee: National Institute of Agrobiological SciencesInventors: Takahiro Kikawada, Takashi Okuda, Masahiko Watanabe, Kazuei Mita, Keiko Kadono

Patent number: 7892789Abstract: There are provided trehalose transporter gene and a method of introducing trehalose into cells by using the gene. Candidates for the trehalose transporter genes were searched in P. vanderplanki EST, resulting in being obtained cDNA designated as Tret1. Tret1 encodes a 504 amino acid protein with 12 trans-membrane structures. Tret1 expression was induced by desiccation stress and predominant in the fat body. Functional expression of TRET1 in Xenopus oocytes showed that transport activity was specific for trehalose and independent of extracellular pH and electrochemical membrane potential. The direction of transport of TRET1 was reversible depending on the concentration gradient of trehalose. Apparent Km and Vmax of TRET1 for trehalose were extraordinarily high values. These results indicate that TRET1 is a facilitated, high-capacity trehalose-specific transporter. Tret1 is widespread in insects. Furthermore, TRET1 conferred trehalose permeability upon cells including those of vertebrates as well as insects.Type: GrantFiled: March 5, 2008Date of Patent: February 22, 2011Inventors: Takahiro Kikawada, Takashi Okuda, Masahiko Watanabe, Ayako Saito, Yasushi Kanamori, Yuichi Nakahara
