Fig. 1.
NS5A domain I directly binds HSP70. The upper part of all panels displays Western analysis of GST pull-down targets (antibodies are mentioned underneath). Arrows indicate presence of target polypeptides. The lower part(s) represent(s) Coomassie stains showing GST-fusion bait proteins. (A) and (B) NS5A directly binds HSP70. (C) Deletion of NS5A domain I abolishes its HSP70 interaction. (D) The membrane anchoring domain of NS5A is not required for HSP70 binding. (E) Only NS5A domain I binds HSP70.
