NKX2-1

该基因编码一种最初被鉴定为甲状腺特异性转录因子的蛋白质。编码的蛋白质与甲状腺球蛋白启动子结合，调节甲状腺特异基因的表达，但也被证明调节与形态发生有关的基因的表达。该基因的突变和缺失与良性遗传性舞蹈病、舞蹈病、先天性甲状腺功能减退和新生儿呼吸窘迫有关，并可能与甲状腺癌有关。已发现该基因编码不同亚型的多个转录变体。该基因与另一个在核糖体基因转录中起作用的基因转录终止因子1共享符号/别名“ttf1”。[由RefSeq提供，2014年2月]
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]
