The homeodomain of the thyroid transcription factor-1 (TTF-1HD) shows a peculiar DNA-binding specificity, preferentially recognizing sequences having the 5'-CAAG-3' core motif. In order to detail the DNA-binding specificity of this protein, a TTF-1HD-Sepharose column chromatography was used. A sequential selection and amplification of sequences was performed. TTF-1HD binding activity for selected and unselected sequences was measured. The presence of the 5'-CAAG-3' core motif was necessary, but not sufficient, to obtain the maximal binding activity for TTF-1HD. However, several of the selected sequences do not contain the 5'-CAAG-3' core motif and are bound by TTF-1HD only 2-fold less with respect to sequences bound with the highest affinity. Therefore, these data indicate that TTF-1HD specifically recognizes a spectrum of sequences wider than previously determined.
