Total cell lysates were prepared following published methods [42 (link)]. Membrane fraction of lysates were prepared with MEM-PER Plus Membrane Protein Extraction Kit (Thermo Fisher Scientific). Immunoblotting was performed as described previously [43 (link)]. Membranes were blocked with 5% skim milk in Tris-buffered saline with Tween (TBST) or Blocking-One reagent (Nacalai Tesque, Kyoto, Japan). Primary antibodies are listed in Supplementary Table S3. Primary antibodies were diluted with TBST or Can Get Signal 1 (Toyobo, Osaka, Japan). Data shown are representative of at least two experiments with similar results, unless otherwise mentioned.
