A human recombinant cDNA clone that encoded 253 amino acids residues of a zinc - finger protein ( THZif - 1 ) was cloned by screening a cDNA library prepared from human promyelocytic leukemia HL60 cells with synthetic oligodeoxynucleotide probes that corresponded to the amino acid sequences of tryptic peptides derived from the DNA - binding protein specific for the nuclease - hypersensitive element ( NHE ) of the human c - myc gene .
