The presence of TN in culture medium does not detectably alter the pattern of tyrosine phosphorylation resulting from T cell triggering with alpha CD3 , but at later time points prevents the appearance of functional NF-AT1 transcription factor complexes in T cell nuclear extracts .
 protein: TN; protein: T cell nuclear extracts; protein: CD3; protein: alpha CD3; protein: NF-AT1 transcription factor complexes
