a HEK293 cells were transfected with TRAF6-Myc, TRAF6-HA, or empty vector. After 24 h post-transfection, the cells were lysed and IP analyses with HA antibody. b HEK293 cells were transfected with TRAF6-Myc, TRAF6-HA, empty vector, or calpain2a-Flag. After 24 h post-transfection, the cells were lysed and IP analyses with HA antibody. c HEK293 cells were transfected with TRAF6-Myc, TRAF6-HA, empty vector, or different concentrations of calpain2a-ΔCysPc-Flag. After 24 h post-transfection, the cells were lysed and IP analyses with HA antibody. d, e HEK293 cells were cotransfected with TRAF6-Myc, TRAF6-HA and WT-ubiquitin-His or K63O-ubiquitin-His (in which only lysine 63 is kept) together with calpain2a-Flag, calpain2a-ΔCysPc-Flag or empty vector. After 24 h post-transfection, the cells were lysed and purified with Ni-NTA agarose. The immunoprecipitates and input immunoblot analysis with anti-Myc, anti-Flag, anti-HA, and anti-Tubulin Abs. All experiments were performed in at least three independent experiments.
