title: Cloning and nucleotide sequence analysis of human embryonic zeta-globin cDNA.
abstract: Clones of human embryonic alpha-like zeta-globin cDNA were isolated, by detection using cross-hybridization to human alpha-globin cDNA probes, from a cDNA library derived from the mRNA of the human erythroleukemia cell line K562. Nucleotide sequence analysis of these cDNA clones revealed a coding sequence that corresponds perfectly to the independently derived amino acid sequence of the human zeta-globin chain. Comparison of the nucleotide sequence of human zeta-globin cDNA with that of human alpha-globin cDNA confirmed previous estimates of very distant evolutionary divergence between the human zeta- and alpha-globin genes. Nevertheless, the human zeta-globin cDNA sequence shares a remarkable similarity to that of the alpha-globin gene in its codon usage, high G + C base composition, and lack of bias against usage of CG dinucleotides.
