TORC1 activity in all eukaryotes is dependent on amino acid availability. However, the mechanism through which TORC1 senses amino acids is still a mystery. In the current issues of Molecular Cell and Cell, Bonfils et al. (2012) and Han et al. (2012) implicate leucyl-tRNA synthetase in this evolving story.
所有真核生物中 TORC1 的活性都依赖于氨基酸的可获得性。然而,TORC1 感知氨基酸的机制仍然是一个谜。在本期的《分子细胞》和《细胞》杂志上,Bonfils 等人(2012)和 Han 等人(2012)将亮氨酰-tRNA 合成酶牵涉到这个不断发展的故事中。
