This is due to alternative splice/polyadenylation events that lead to the predominant synthesis of two long isoforms in naive T cells and a shorter NF-ATc isoform in effector T cells .
 ( protein: NF-ATc, None) , ( protein: NF-ATc isoform, None) , ( cell type: naive T cells, None) , ( cell type: effector T cells, None)
