Abstract
Deubiquitinases are widely involved in the regulation of the virus-triggered type I interferon (IFN) signaling. Here, we found sea perch (Lateolabrax japonicus) ubiquitin-specific protease 5 (LjUSP5) was a negative regulatory factor of the red-spotted grouper nervous necrosis virus (RGNNV)-triggered IFN response. LjUSP5 encoded a polypeptide of 830 amino acids, containing a zinc finger UBP domain (residues 197-270 aa), two ubiquitin-associated domains (residues 593-607 aa; 628-665 aa), and one UBP domain (residues 782-807 aa), and shared the closest genetic relationship with the USP5 of Larimichthys crocea. Quantitative RT-PCR analysis showed that LjUSP5 was ubiquitously expressed and up-regulated significantly in all inspected tissues post RGNNV infection, and its transcripts significantly increased in brain, liver and kidney tissues post RGNNV infection. LjUSP5 was up-regulated in cultured LJB cells after poly I:C and RGNNV treatments. In addition, overexpression of LjUSP5 significantly inhibited the activation of zebrafish IFN 1 promoter and promoted RGNNV replication in vitro. Furthermore, LjUSP5 inhibited the activation of zebrafish IFN 1 promoter induced by key genes of retinoic acid-inducible gene I-like receptors signaling pathway. Our findings provides useful information for further elucidating the mechanism underlying NNV infection.
