tokens: Based on the hypothesis that evolutionarily conserved regions are functionally important and likely to interact with coactivators , we compared the amino acid sequence of C / EBPalpha from different species ( frog to human ) and identified four highly conserved regions ( CR1-CR4 ) within the transactivation domain .
