Analysis on the Molecular Biologic Characteristics and Expression of Lysozyme C Separated from Oplegnathus fasciatus

Background and Aim: lysozyme has been known as a significant component of the innate immune system of fish. It is reported that the g-type and c-type lysozymes have been identified in fish. Oplegnathus fasciatus is one of the economically important cultured species, generating higher market value and demands in Korea. Contrary to the heavy consumption of O. fasciatus, however, there has been very limited information on their immune system and immunity genes responding against diseases. Methods: This study clarified the molecular biological characteristics of cDNA of the C-type lysozyme from O. fasicatus and conducted phylogency analysis. Furthermore, tissue-specific expression analysis of genes verified the roles of c-type lysozyme in general circumstances.
