By using a reverse transcription-PCR-based approach and a set of primers specific for the DNA-binding domains of highly homologous members of the C/EBP family of transcriptional regulators , we have cloned a novel human gene encoding a member of the C/EBP gene family , identified as the human homolog of CRP1 , C/EBP-epsilon .
 ( protein: transcriptional regulators, None) , ( DNA: C/EBP gene family, None) , ( protein: CRP1, None) , ( DNA: novel human gene, None) , ( DNA: DNA-binding domains, None) , ( protein: C/EBP-epsilon, None) , ( protein: C/EBP family, None)
