TRIM8 catalyses PEDV N protein degradation via K48-linked ubiquitination. A Co-IP and IB analysis of HEK293T cells expressing HA-tagged PEDV N protein and increasing amounts of TRIM8. B IB analysis of cells expressing HA-tagged PEDVN with or without TRIM8 under CHX treatment for different time points (0, 9, 12, 15Â h). CHX: Cycloheximide. C IB analysis of cells expressing HA-tagged PEDV N under the treatment of proteasome inhibitor MG132 for 12Â h. D IB analysis of cells expressing HA-tagged PEDV N under the treatment of autophagy-lysosome inhibitor Leupeptin for 12Â h. E Co-IP and IB analysis of MG132-treated cells expressing MYC-tagged PEDV N, with or without TRIM8, HA-tagged wild-type ubiquitin, mutant ubiquitin K48 and K63. WCL: whole cell lysates.
