Because transgene expression was regulated by the proximal promoter of the murine lck gene and this promoter is inactivated in T cells that exit the thymus , the mutant hCaMKIV is not present in peripheral T cells .
 ( DNA: murine lck gene, None) , ( protein: mutant hCaMKIV, None) , ( DNA: proximal promoter, None) , ( cell type: T cells, None) , ( cell type: peripheral T cells, None)
