英文摘要In the present study, a ubiquitin (designated as RpUbi) was identified and characterized from clam Ruditapes philippinarum. Phylogenetic analysis strongly suggested that RpUbi was a member of the ubiquitin family. In nonstimulated clams, RpUbi transcripts were constitutively expressed in all examined tissues, especially in the gills and hemocytes. After Vibrio anguillarum challenge, expression of RpUbi mRNA in hemocytes was significantly upregulated. Recombinant RpUbi (rRpUbi) showed high antibacterial activity against Gram-positive and Gramnegative bacteria. Notably, membrane integrity and electrochemical assay indicated that rRpUbi could invade the inner layer. Moreover, DNA migration could be inhibited by rRpUbi in a concentration-dependent manner. In general, our results suggested that RpUbi played an important role in host defense against invading bacteria, perhaps through a DNA-binding process.
