Abstract
The teleost warm temperature acclimation related 65 kDa protein Wap65 is a plasma glycoprotein with the potential roles in heat adaptation heme recycling immune response and copper metabolism It is most homologous to the mammalian hemopexin which is the plasma transporter of heme A fulllength cDNA clone of the Wap65 gene 1534 bp in size was isolated from the fish ayu Plecoglossus altivelis Its deduced amino acid sequence of 439 residues had 604–654 and 383–473 identical to fish Wap652type and Wap651type sequences respectively In phylogenetic analysis aWap65 grouped tightly with those fish Wap652type sequences In healthy control fish the highest mRNA signal for aWap65 was from the liver moderately high in brain and gill and but weaker in spleen kidney muscle heart and intestine In Listonella anguillaruminfected fish aWap65 transcripts were significantly increased in liver while no obvious changes in other tissues at 12 hpi However aWap65 transcripts were significantly increased in various tissues at 24 hpi when hemolysis developing suggesting that aWap65 might be involved in the immune response of ayuWe thank Dr M J Adams Rothamsted Research Harpenden UK for help in correcting the English of the manuscript The project was supported by the 973 Program 2008CB117015 the ST Programme of Ningbo SciTech Bureau 2007C10081 2007A31004 the Program for Changjiang Scholars and Innovative Research Team in University PCSIRT IRT0734 and the KC Wong Magna Fund in Ningbo University
