AbstractTBK1 has been extensively studied in mammals because of its important roles as a molecular bridge, linking the TLRs (TLR3 and TLR4) and RLRs signals to activate transcriptional factors IRF3 and IRF7 for IFN-I production. However, the information on molecular and functional characteristics of TBK1 in teleosts is limited. In this study, the molecular characterization and immune response of TBK1 in Larimichthys crocea (named as LcTBK1) as well as its interaction with Nrdp1 were investigated. Sequence analysis demonstrated that LcTBK1 included four functional motifs, the N-terminal protein kinase domain and ATP-binding site, middle ULD and C-terminal coiled-coil domain. The tissue expression profiles indicated that LcTBK1 gene was constitutively expressed in the twelve tissues examined, with high expression in brain. Temporal expression analysis showed that LcTBK1 mRNA was obviously increased in the liver after injection of LPS, Poly I:C and inactive Vibrio parahaemolyticus, however, declined at some time points in spleen and head-kidney. Furthermore, we found that LcTBK1 can interact with LcNrdp1, an E3 ubiquitin ligase that involved in immune response to Cryptoccuyon irritans infection in L. crocea. The qPCR showed that LcNrdp1 was also significantly up-regulated in liver, down-regualted at some time points in spleen and head-kidney after LPS, Poly I:C and inactive V. parahaemolyticus injection, although the expression patterns of the two genes after the three treatments were different in change magnitude and up-regulation timespan. These results suggested that LcTBK1 was involved in L. crocea defense against the pathogen infection and can be regulated by Nrdp1 in PPRs signaling pathway of fishes. (C) 2015 Elsevier Ltd.
