Utilization of Thyroid Transcription Factor-1 Immunostaining in the Diagnosis of Lung Tumors

only in those cells. Thyroid transcription factor-1 (TTF-1) is a 38-kDa homeodomain containing nuclear transcription protein of the Nkx2 gene family. It consists of a single polypeptide of 371 amino acids that is encoded by a single locus (2 ). TTF-1 is expressed

, vitamin D, retmoic acid and thyroid hormone (7 ). The p65 protein is highly homologous to estrogen receptor (ER) m its DNA binding domain but other regions of the sequence do not show similarities, indicating that p65 is a new transcription factor

of galactose induction steps and increasing the amount of Gal4p transcription factor both improved expression. Lowering the temperature from 28 to 18�C during expression enhanced the recovery of detergent-extractible active protein. In the “light membrane
