| Tbio | Homeobox protein Nkx-2.1 |
Transcription factor that binds and activates the promoter of thyroid specific genes such as thyroglobulin, thyroperoxidase, and thyrotropin receptor. Crucial in the maintenance of the thyroid differentiation phenotype. May play a role in lung development and surfactant homeostasis. Forms a regulatory loop with GRHL2 that coordinates lung epithelial cell morphogenesis and differentiation. Activates the transcription of GNRHR and plays a role in enhancing the circadian oscillation of its gene expression. Represses the transcription of the circadian transcriptional repressor NR1D1 (By similarity).
This gene encodes a protein initially identified as a thyroid-specific transcription factor. The encoded protein binds to the thyroglobulin promoter and regulates the expression of thyroid-specific genes but has also been shown to regulate the expression of genes involved in morphogenesis. Mutations and deletions in this gene are associated with benign hereditary chorea, choreoathetosis, congenital hypothyroidism, and neonatal respiratory distress, and may be associated with thyroid cancer. Multiple transcript variants encoding different isoforms have been found for this gene. This gene shares the symbol/alias 'TTF1' with another gene, transcription termination factor 1, which plays a role in ribosomal gene transcription. [provided by RefSeq, Feb 2014]

| 26356687 | Mutations of TTF1 is associated with risk of Papillary Thyroid Cancer in Chinese. Patients with Multiplendular goiter and no metastasis are more likely to suffer PTC. C/T variant of TTF1 had a high correlation with PTC in the overall population. |
| 26337230 | Preoperative serum miR-365 and TTF-1 mRNA levels may be effective indicators of tumor aggressiveness in human NSCLC. miR-365 and its target gene TTF-1 appear to be synergistic risk factors for the reduction in overall survival of patients with NSCLC. |
