1 Studies reported here evaluated the differential regulation and function of the two transcripts and protein products of RCAN1 by the synthetic GC dexamethasone (Dex), and by modulators of calcium signaling. Dexamethasone regulator of calcineurin 1 Homo sapiens

3 RESULTS: Dex selectively upregulates transcript specific for RCAN 1-1 in glucocorticoid (GC)-susceptible human leukemic CEM-C7-14 cells but not in GC-refractory CEM-C1-15 sister cells. Dexamethasone regulator of calcineurin 1 Homo sapiens
4 Expression of the second major transcript, RCAN1-4, is upregulated by [Ca2+]i inducers, thapsigargin and A23187, but not by Dex, suggesting a mutually exclusive regulatory pathway for both RCAN1 transcripts. Thapsigargin regulator of calcineurin 1 Homo sapiens

9 RCAN1-1 coimmunoprecipitates with calcineurin PP3C and Dex-mediated RCAN1-1 upregulation correlated with reduction in calcineurin PP3C activity. Dexamethasone regulator of calcineurin 1 Homo sapiens
10 RCAN1-1 coimmunoprecipitates with calcineurin PP3C and Dex-mediated RCAN1-1 upregulation correlated with reduction in calcineurin PP3C activity. Dexamethasone regulator of calcineurin 1 Homo sapiens
