Using a previously described mutant of the Jurkat T cell line , we show that proximal signaling events dependent on the presence of the CD45 tyrosine phosphatase are required for TCR -stimulated CD95 ligand expression .
 ( protein: CD95 ligand, None) , ( cell line: Jurkat T cell line, None) , ( protein: CD45 tyrosine phosphatase, None) , ( protein: TCR, None) 
Locate the role in the text that participated in the event based on the event type and return it in the event list. 
 Option: Event type: RNA,cell type,protein,cell line,DNA, Arguments type: .
