Isolation and characterization of the canine thyroglobulin gene promoter region.
The 5' flanking sequences from the canine thyroglobulin gene were isolated by homology screening with the evolutionary conserved sequence from the bovine thyroglobulin promoter and sequenced. Transient expression in primary cultured dog thyrocytes demonstrated that the canine clone contains a functional promoter inducible by cAMP. DNAse I footprinting assays showed that the thyroid-specific transcription factor TTF-1, purified from bovine thyroid, also recognizes the canine thyroglobulin promoter. Similar footprints were obtained with crude nuclear extracts from primary cultured dog thyrocytes.
