TXNIP基因编码的功能和结构描述
该基因编码硫氧还蛋白结合蛋白，其是α-抑制素蛋白家族的成员。硫氧还蛋白是一种巯基氧化还原酶，它是细胞氧化还原信号的主要调节器，它保护细胞免受氧化应激。这种蛋白质抑制硫氧还蛋白的抗氧化功能，导致活性氧的积累和细胞应激。该蛋白还可以调节细胞代谢和内质网应激。这种蛋白质也可以作为一种肿瘤抑制因子。交替剪接导致多个转录变体。
This gene encodes a thioredoxin-binding protein that is a member of the alpha arrestin protein family. Thioredoxin is a thiol-oxidoreductase that is a major regulator of cellular redox signaling which protects cells from oxidative stress. This protein inhibits the antioxidative function of thioredoxin resulting in the accumulation of reactive oxygen species and cellular stress. This protein also functions as a regulator of cellular metabolism and of endoplasmic reticulum (ER) stress. This protein may also function as a tumor suppressor. Alternate splicing results in multiple transcript variants.
