TGT3, thyroid transcription factor I, and Sp1 elements regulate transcriptional activity of the 1.3-kilobase pair promoter of T1alpha, a lung alveolar type I cell gene.

Abstract excerpt

Alveolar type I epithelial cells form the major surface for gas exchange in the lung. To explore how type I cells differ in gene expression from their progenitor alveolar type II cells, we analyzed transcriptional regulation of T1alpha, a gene expressed by adult type I but not type II cells. In vivo developmental patterns of T1alpha expression in lung and brain suggest active gene regulation. We cloned and...
