Constitutively active MAPKK-1 fully activates ERK-2 and the transcription factor Elk-1 , but does not substitute for activated p21ras and synergize with calcium /calcineurin signals to induce NFAT .
 ( protein: MAPKK-1, None) , ( protein: transcription factor, None) , ( protein: NFAT, None) , ( protein: Elk-1, None) , ( protein: p21ras, None) , ( protein: ERK-2, None) , ( protein: /calcineurin, None)
