这个基因编码的蛋白质属于谷胱甘肽过氧化物酶家族,该家族成员通过谷胱甘肽催化有机羟过氧化物和过氧化氢(H2O2)的还原,从而保护细胞免受氧化损伤。这个基因家族在脊椎动物中存在几种同工酶,它们的细胞定位和底物特异性各不相同。这个同工酶在啮齿动物的胃肠道中主要表达,位于细胞质中,其偏好底物是过氧化氢。缺乏这个基因的小鼠的敲除研究表明,这个同工酶在肠道炎症和结肠癌发展中有作用。这个同工酶也是一种硒蛋白,在其活性部位含有罕见的氨基酸硒代半胱氨酸(Sec)。Sec由UGA密码子编码,该密码子通常表示翻译终止。硒蛋白mRNA的3'UTR含有一个保守的茎环结构,称为Sec插入序列(SECIS)元素,该元素对于识别UGA作为Sec密码子而不是作为停止信号是必要的。这个位点的假基因已经在染色体7上被鉴定。[RefSeq,2017年8月提供]
