We therefore propose a model whereby a core NFAT complex consisting of Jun , Fos , and a constitutive nuclear factor is formed in both T and B cells , but an additional factor and/or post-translational modification of a factor, missing in B cells , might be required for transactivation by NFAT .
 ( protein: NFAT complex, None) , ( protein: Fos, None) , ( protein: NFAT, None) , ( protein: NFAT, None) , ( protein: constitutive nuclear factor, None) , ( cell type: B cells, None) , ( protein: Jun, None)
