To ascertain whether the abnormal NF-AT binding activity was related to an impaired function, we transfected patient and control T lymphocytes with constructs containing the reporter gene encoding chloramphenicol acetyl transferase ( CAT ) under the control of the entire IL2 regulatory region or of multimers of individual enhancer sequences .
 ( DNA: IL2, None) , ( DNA: enhancer sequences, None) , ( protein: chloramphenicol acetyl transferase, None) , ( protein: NF-AT, None) , ( DNA: IL2 regulatory region, None) , ( protein: CAT, None) , ( cell type: T lymphocytes, None)
