摘要: Yersinia encodes a protein kinase, YpkA, which disrupts the actin cytoskeleton. Using an approach termed chemical genetics, we identified 36-kDa substrate for YpkA in both J774 lysates and bovine brain cytosol. Mass spectrometry analysis this as FLJ20113, open reading frame that corresponds to otubain 1, deubiquitinating enzyme implicated immune cell clonal anergy. We demonstrate 1 is phosphorylated by vitro interacts with vivo. Identification of suggests regulation anergy may be survival mechanism Yersinia.
