Background

Tuberin is a product of the TSC2 tumor suppressor gene and an important regulator of cell proliferation and tumor development (1). Mutations in either TSC2 or the related TSC1 (hamartin) gene cause tuberous sclerosis complex (TSC), an autosomal dominant disorder characterized by development of multiple, widespread non-malignant tumors (2). Tuberin is directly phosphorylated at Thr1462 by Akt/PKB (3). Phosphorylation at Thr1462 and Tyr1571 regulates tuberin-hamartin complexes and tuberin activity (3-5). In addition, tuberin inhibits the mammalian target of rapamycin (mTOR), which promotes inhibition of p70 S6 kinase, activation of eukaryotic initiation factor 4E binding protein 1 (4E-BP1, an inhibitor of translation initiation), and eventual inhibition of translation (3,6,7).

马铃薯球蛋白(Tuberin)是TSC2肿瘤抑制基因的产物,是细胞增殖和肿瘤发展的重要调节因子(1)。TSC2或与之相关的TSC1(hamartin)的突变可以引起结节硬化复合体TSC(tuberous sclerosis complex),是一种常染色体显性遗传病,其特点为发生多种广泛的非恶性肿瘤(2)。Tuberin可以在Thr1462位点直接被Akt/PKB 磷酸化(3)。 在Thr1462 和 Tyr1571位点的磷酸化可以调节tuberin-hamartin复合体和tuberin的活性(3-5)。另外,tuberin可以抑制mTOR(mammalian target of rapamycin), 进而推动p70 S6激酶的抑制和真核细胞抑制因子4E结合蛋白(4E-BP1,一种转录起始抑制因子)的活性,并最终抑制翻译(3,6,7)。
