Protein
Homeobox protein Nkx-2.1
Gene
Nkx2-1, Nkx-2.1, Titf1, Ttf1
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

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. 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 NR1D1.1 Publication
