The close homology of the basic region/leucine zipper ( bZIP ) DNA-binding and dimerization domain of HLF to that of the CES-2 cell-death specification protein of Caenorhabditis elegans suggests a model of leukaemogenesis in which E2A-HLF blocks an early step within an evolutionarily conserved cell-death pathway .
 ( protein: HLF, None) , ( protein: dimerization domain, None) , ( protein: bZIP, None) , ( protein: CES-2 cell-death specification protein, None) , ( protein: E2A-HLF, None) , ( protein: basic region/leucine zipper, None)
