Consistent with this, we found YpkA to be present in the same protein complex as OTUB1 in living cells and during bacterial invasion, as assessed by co-immunoprecipitation. Moreover, ... during Yersinia invasion [19]. In addition to its serine ⁄ threonine kinase activity [13,15,37] and binding to actin [12], YpkA has been show...
