摘要 | Macrophage-expressed gene 1 (MPEG1) is an ancient immune effector known to exist in Cnidaria, Mollusca, Actinopterygii, and Mammalia. In this study, we examined the evolution and antibacterial potential of MPEG1 across Metazoa. By unbiased data-mining, MPEG1 orthologs were found in 11 of 34 screened phyla. In invertebrates, MPEG1 is present in the major phyla and exhibits intensive duplication. In vertebrates, class-based clades were formed by the major, generic MPEG1 (gMPEG1) in each class. However, there is a minority of unique MPEG1 (uMPEG1) from 71 species of 4 classes that clustered into a separate clade detached from all major classbased clades. gMPEG1 and uMPEG1 exhibit strong genomic collinearity and are surrounded by high-density transposons. gMPEG1 and uMPEG1 transcript expressions were most abundant in immune organs, but differed markedly in tissue specificity. Systematic analysis identified an antimicrobial peptide (AMP)-like segment in the C-terminal (CT) tail of MPEG1. Peptides based on the AMP-like regions of 35 representative MPEG1 were synthesized. Bactericidal activities were displayed by all peptides. Together these results suggest transposonpropelled evolutionary diversification of MPEG1 in Metazoa that has likely led to functional specialisation. This study also reveals a possible antimicrobial mechanism mediated directly and solely by the CT tail of MPEG1. |
