Gene Structure and Expression of Human Thyroid Transcription Factor-1 in Respiratory Epithelial Cells

Abstract excerpt

The human gene encoding thyroid transcription factor-1 (TTF-1), a homeodomain-containing nuclear transcription protein of the Nkx2 gene family, was isolated and characterized. Human TTF-1 was encoded by a single gene locus spanning approximately 3.3 kilobases and consisted of two exons and a single intron. The TTF-1 cDNA and polypeptide of 371 amino acids have been highly conserved, sharing 98% identity with the...
