CC -!- FUNCTION: Transcription factor that binds and activates the promoter of
CC thyroid specific genes such as thyroglobulin, thyroperoxidase, and
CC thyrotropin receptor. Crucial in the maintenance of the thyroid
CC differentiation phenotype. May play a role in lung development and
CC surfactant homeostasis. Forms a regulatory loop with GRHL2 that
CC coordinates lung epithelial cell morphogenesis and differentiation.
CC Activates the transcription of GNRHR and plays a role in enhancing the
CC circadian oscillation of its gene expression. Represses the
CC transcription of the circadian transcriptional repressor NR1D1 (By
CC similarity). {ECO:0000250|UniProtKB:P23441,

CC -!- DISEASE: Chorea, hereditary benign (BHC) [MIM:118700]: A rare autosomal
CC dominant movement disorder, defined by early onset in childhood, a
CC stable or non-progressive course of chorea, and no mental
CC deterioration. Chorea is characterized by involuntary, forcible, rapid,
CC jerky movements that may be subtle or become confluent, markedly
CC altering normal patterns of movement. {ECO:0000269|PubMed:11971878,

CC affecting the gene represented in this entry.
CC -!- DISEASE: Choreoathetosis and congenital hypothyroidism with or without
CC pulmonary dysfunction (CAHTP) [MIM:610978]: An autosomal dominant
CC disorder that manifests in infancy with neurological disturbances,
CC hypothyroidism, and respiratory problems. It is characterized by
CC movement abnormalities beginning with muscular hypotonia followed by
CC the development of chorea, athetosis, dystonia, ataxia, and dysarthria.

CC affecting the gene represented in this entry.
CC -!- DISEASE: Thyroid cancer, non-medullary, 1 (NMTC1) [MIM:188550]: A form
CC of non-medullary thyroid cancer (NMTC), a cancer characterized by
CC tumors originating from the thyroid follicular cells. NMTCs represent
CC approximately 95% of all cases of thyroid cancer and are classified
CC into papillary, follicular, Hurthle cell, and anaplastic neoplasms.
CC {ECO:0000269|PubMed:19176457}. Note=Disease susceptibility is
CC associated with variants affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the NK-2 homeobox family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
