AbstractPeptidoglycan recognition proteins (PGRPs), which are evolutionarily conserved from invertebrates to vertebrates, function as pattern-recognition and effector molecules in innate immunity. In the present study, a short-form PGRP, designated as HcPGRPS1 was identified from freshwater mussel Hyriopsis cumingi. The deduced amino acid sequence of HcPGRPS1 is composed of 235 residues which contains a conserved PGRP domain at the C-terminus. Sequence analysis showed that HcPGRPS1 shared high identities with other known PGRPs. The mRNA of HcPGRPS1 is constitutively expressed in a wide range of all tested tissues, with highest expression level in hepatopancreas, and its expression in tissues (gonad, nephridium, gill and foot) was up-regulated significantly after LPS or PGN stimulation (P<0.05). The recombinant protein of HcPGRPS1 exhibited binding activity and peptidoglycan-lytic amidase activity toward Lys-PGN from Staphylococcus aureus and DAP-PGN from Bacillus subtills. Furthermore, recombinant HcPGRPS1 displayed strong antibacterial activity to both Gram-negative bacteria Escherichia coli, Aeromonas hydrophila, Aeromonas sobria and Gram-positive bacteria S. aureus in the presence of Zn2+. These results suggested that HcPGRPS1 plays a multifunctional role in the defense and protection mechanisms of mussel innate immunity against infections. (C) 2013 Elsevier Ltd.
