PG - 105-112 LID - S0034-5288(19)30340-6 [pii] LID - 10.1016/j.rvsc.2019.10.004 [doi] AB - Porcine reproductive and respiratory syndrome (PRRS) caused by PRRS virus (PRRSV), has ranked among the major economically significant pathogen in the global swine industry. The PRRSV nonstructural protein (nsp)11 possesses nidovirus endoribonuclease (NendoU) activity, which is important for virus replication and suppression of the host innate immunity system. Recent proteomic study found that TRIM59 (tripartite motif-containing 59) interacted with the nsp11, albeit the exact role it plays in PRRSV infection remains enigmatic. Herein, we first confirmed the interaction between nsp11 and TRIM59 in co-transfected HEK293T cells and PRRSV-infected pulmonary alveolar macrophages (PAMs). The interacting domains between TRIM59 and nsp11 were further determined to be the N-terminal RING domain in TRIM59 and the C-terminal NendoU domain in nsp11, respectively. Moreover, we reported that overexpression of TRIM59 inhibited PRRSV infection in Marc-145 cells. Conversely, small interfering RNA (siRNA) depletion of TRIM59 resulted in enhanced production of PRRSV in PAMs. Together, these data add TRIM59 as a crucial antiviral component against PRRSV and provide new insights for development of new compounds to reduce PRRSV infection.
