The DNA-binding sites for transcriptional regulator GATA-6 were selected and amplified by means of a PCR-mediated random-site selection method involving filter binding and gel-mobility shift analysis using the zinc finger region of human GATA-6 fused with GST. Sequencing and comparison of the selected clones suggested that (A/T/C)GAT(A/T)(A) is the consensus binding sequence, which is similar to the GATA motif (A/T)GATA(A/G) and the gastric motif (G/C)PuPu(G/C)NGAT(A/T)PuPy. GATA-6 also binds to a similar sequence containing the GATC but not the GATG sequence. These results indicated that GATA-6 shows broader sequence specificity as to DNA binding. However, adenine is favored on both sides of the core for strong binding [AGAT(A/T)A], and the order of binding is GATA > GATT > GATC. Full-length human GATA-6 expressed in COS-1 cells showed essentially the same binding specificity, suggesting that the zinc finger region of GATA-6 mainly contributes to the selection of the binding sequence. Furthermore, the non-RI method presented in this paper is convenient for determination of the binding sites of other DNA-binding proteins.
