| 中文摘要 | Peptidoglycan recognition proteins (PGRPs), which are evolutionarily conserved from insects to mammals, recognize bacterial peptidoglycan (PGN) and function in antibacterial innate immunity. In this study, a short-form PGRP, designated as gcPGRP5 was identified from grass carp Ctenopharyngodon idella. The deduced amino acid sequence of gcPGRP5 is composed of 180 residues with a conserved PGRP domain at the C-terminus. The gcPGRP5 gene consists of four exons and three introns, spacing approximately 2.3 kb in genomic sequence. Phylogenetic analysis demonstrated that the gcPGRP5 is clustered with other PGRP-S identified in teleost fish. The gcPGRP5 is constitutively expressed in all organs/tissues examined, and its expression was significantly induced in CIK cells treated with lipoteichoic acid (LTA), polyinosinic polycytidylic acid (Poly I:C) and PGN. Fluorescence analysis showed that gcPGRP5 is distributed in cytoplasm of CIK cells, and cell lysates from CIK cells transfected with pTurbo-gcPGRP5-GFP and ptGFP1-gcPGRP5 plasmids display the binding activity and peptidoglycan-lytic amidase activity toward Lys-PGN from Staphylococcus aureus and Dap-PGN from Bacillus subtilis. Furthermore, heat-shock protein70 (Hsp70), and MyD88, an adaptor molecule in Toll-like receptor pathway, had an increased expression in CIK cells overexpressed with gcPGRP5. It is thus indicated that gcPGRP5 exhibits amidase activity, and also possesses roles in anti-stress, and in Toll-like receptor signaling pathway. (C) 2013 Elsevier Ltd. All rights reserved. |
