哺乳动物雷帕霉素靶蛋白复合物1(mTOR 1)是一种重要的、高度保守的细胞生长调节因子。在调节mTORC 1的信号中,营养素是最古老的。氨基酸将mTORC 1引导至晚期内体/溶酶体的表面,在那里mTORC 1变得接受其他输入。然而,内体和mTORC 1之间的相互作用知之甚少。在这里,我们报告了一个网络的发现,连接mTORC 1的一个关键组成部分的晚期内体/溶酶体,V-ATP酶。在一个公正的屏幕上,我们发现,mTORC 1调节的表达,在其他溶酶体基因,V-ATP酶。mTORC 1调节细胞和小鼠中V-ATP酶的表达。mTORC 1对V-ATP酶的调节涉及肾癌中易位的转录因子TFEB。TFEB是mTORC 1应答基因的一个大子集的表达所必需的。mTORC 1协调调节TFEB磷酸化和核定位,并且以依赖于TFEB和V-ATP酶的方式,mTORC 1促进内吞作用。这些数据揭示了一个调控网络,连接致癌转录因子,是一个主调节溶酶体生物发生,TFEB,mTORC 1和内吞作用。
Mammalian target of rapamycin (mTOR) complex 1 (mTORC1) is an important, highly conserved, regulator of cell growth. Ancient among the signals that regulate mTORC1 are nutrients. Amino acids direct mTORC1 to the surface of the late endosome/lysosome, where mTORC1 becomes receptive to other inputs. However, the interplay between endosomes and mTORC1 is poorly understood. Here, we report the discovery of a network that links mTORC1 to a critical component of the late endosome/lysosome, the V-ATPase. In an unbiased screen, we found that mTORC1 regulated the expression of, among other lysosomal genes, the V-ATPases. mTORC1 regulates V-ATPase expression both in cells and in mice. V-ATPase regulation by mTORC1 involves a transcription factor translocated in renal cancer, TFEB. TFEB is required for the expression of a large subset of mTORC1 responsive genes. mTORC1 coordinately regulates TFEB phosphorylation and nuclear localization and in a manner dependent on both TFEB and V-ATPases, mTORC1 promotes endocytosis. These data uncover a regulatory network linking an oncogenic transcription factor that is a master regulator of lysosomal biogenesis, TFEB, to mTORC1 and endocytosis.
