On the basis of binding , reconstitution and cotransfection experiments , we propose that activation of NF-AT occurs in at least two stages: a CsA -sensitive stage involving modification and/or translocation of the pre-existing NF-AT complex , and a CsA -insensitive stage involving the addition of newly synthesized Fos or Fos/Jun proteins to the pre-existing complex .
 protein: NF-AT; protein: pre-existing complex; protein: Fos; protein: NF-AT; protein: NF-AT complex; protein: Fos/Jun proteins
