功能概要

该基因编码的蛋白质属于碘甲腺原氨酸脱碘酶家族。它通过外环 5'-脱碘作用催化激素原甲状腺素 (3,5,3',5'-四碘甲状腺原氨酸,T4) 转化为具有生物活性的甲状腺激素 (3,5,3'-三碘甲状腺原氨酸,T3) 。该基因广泛表达,包括在甲状腺和大脑中。它被认为负责 T3 的“局部”产生,因此对影响这些组织中的甲状腺激素作用很重要。据报道,它在 Graves 病患者的甲状腺和滤泡性腺瘤中也有高度表达。通过这种酶将甲状腺内 T4 转化为 T3 可能显着促进这些患者甲状腺 T3 产生的相对增加。该蛋白质是一种含非标准氨基酸硒代半胱氨酸 (Sec) 的硒蛋白,它由通常发出翻译终止信号的 UGA 密码子编码。硒蛋白 mRNA 的 3' UTR 包含一个保守的茎环结构,称为 Sec 插入序列 (SECIS) 元件,这是将 UGA 识别为 Sec 密码子而不是终止信号所必需的。与该酶家族的其他两个成员 (DIO1 和 DIO3) 不同,该基因的 mRNA 包含一个额外的框内 UGA 密码子,据报道 (在人类中) 该密码子可作为 Sec 或终止密码子发挥作用,这可能导致在具有一个或两个 Sec 残基的两种同种型中;然而,只有上游 Sec (与在 DIO1 和 DIO3 的活性位点发现的单个 Sec 残基保持一致) 被证明对酶活性至关重要 (PMID:10403186) 。已经描述了该基因的可变剪接转录物变体。[RefSeq 提供,2018 年 10 月]

The protein encoded by this gene belongs to the iodothyronine deiodinase family. It catalyzes the conversion of prohormone thyroxine (3,5,3',5'-tetraiodothyronine, T4) to the bioactive thyroid hormone (3,5,3'-triiodothyronine, T3) by outer ring 5'-deiodination. This gene is widely expressed, including in thyroid and brain. It is thought to be responsible for the 'local' production of T3, and thus important in influencing thyroid hormone action in these tissues. It has also been reported to be highly expressed in thyroids of patients with Graves disease, and in follicular adenomas. The intrathyroidal T4 to T3 conversion by this Enzyme may contribute significantly to the relative increase in thyroidal T3 production in these patients. This protein is a selenoprotein containing the non-standard amino acid, selenocysteine (Sec), which is encoded by the UGA codon that normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. Unlike the Other two members (DIO1 and DIO3) of this Enzyme family, the mRNA for this gene contains an additional in-frame UGA codon that has been reported (in human) to function either as a Sec or a stop codon, which can result in two isoforms with one or two Sec residues; however, only the upstream Sec (conserved with the single Sec residue found at the active site in DIO1 and DIO3) was shown to be essential for Enzyme activity (PMID:10403186). Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2018]
