基因 TSHR 与疾病

THSR指导合成促甲状腺激素(TSH)受体,与TSH结合。该受体跨越甲状腺滤膜细胞的细胞膜,很大一部分位于细胞的外表面,一小部分在细胞的内表面。已发现若干个突变位点,突变导致跨膜受体无法跨膜,被保留在细胞内部,受检者对甲状腺激素刺激不敏感,一些病例发展成先天性甲状腺功能减退症。

TSHR thyroid stimulating hormone receptor 14q31 10 约4400 bp
基因摘要 The protein encoded by this gene is a membrane protein and a major controller of thyroid cell metabolism. The encoded protein is a receptor for thyrothropin and thyrostimulin, and its activity is mediated by adenylate cyclase. Defects in this gene are a cause of several types of hyperthyroidism. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008].
