Structure/function analysis of various Oct-2a effector regions in the context of the GAL4 DNA-binding domain revealed that Oct-2a contains two functionally different activation domains at the N and the C termini .
 ( protein: activation domains, None) , ( protein: GAL4 DNA-binding domain, None) , ( protein: Oct-2a effector regions, None) , ( protein: Oct-2a, None) , ( protein: Oct-2a, None)
