SESN3（sestrin 3），癌症关联基因，基因ID：143686，该基因编码应激诱导蛋白的sestrin家族的一个成员。编码的蛋白降低了racα-丝氨酸/苏氨酸蛋白激酶（akt）下游激活ras和foxo转录因子诱导的细胞内活性氧的水平。该蛋白是正常调节血糖、胰岛素抵抗所必需的，在肥胖中起着脂质储存的作用选择性剪接导致多个转录变体[由RefSeq提供，2012年10月]This gene encodes a member of the sestrin family of stress-induced proteins. The encoded protein reduces the levels of intracellular reactive oxygen species induced by activated Ras downstream of RAC-alpha serine/threonine-protein kinase (Akt) and FoxO transcription factor. The protein is required for normal regulation of blood glucose， insulin resistance and plays a role in lipid storage in obesity. Alternative splicing results in multiple transcript variants.
