TRIP promoted K48-linked polyubiquitination of TAK1 in RA-FLS. Extracts of control RA-FLS and RA-FLS stably overexpressed TRIP or TRIPCA stimulated with TNFα (100 ng/mL) for 120 min were subjected to immunoprecipitation with anti-TAK1 and immunoblot analysis with antibody specific for K48-linked ubiquitin. Mg132, proteasome inhibitor. WCL, whole cell lysates.
