We present the cloning and sequencing of the gene encoding the chicken
CCAAT/Enhancer Binding Protein alpha (cC/EBP alpha). The coding regio
n and 1.5 kb of 5' flanking DNA form a CpG island. Comparison of the c
hicken C/EBP alpha sequence to the homologous proteins of other specie
s reveals several evolutionary conserved regions. cC/EBP alpha mRNA ex
pression is restricted to a subset of tissues with high expression in
liver, lung and small intestine. Recombinant cC/EBP alpha binds to its
cognate C/EBP binding site as a homodimer or as a heterodimer with th
e related cC/EBP beta/NF-M. (C) 1997 Elsevier Science B.V.
