Due to a switch from the use of a 3' polyA site to a more proximal polyA site , NF-ATc expression switches from the synthesis of the two longer isoforms in naive T cells to that of short isoform A in T effector cells .
 cell type: T effector cells; DNA: proximal polyA site; protein: NF-ATc; protein: isoform A; DNA: 3' polyA site; cell type: naive T cells
