NOVEL USE OF LEUCYL TRNA SYNTHETASE

摘要

The present invention relates to novel use of leucyl tRNA synthetase and more particularly it relates a method of screening an agent for preventing or treating mTORCl mediated diseases by screening an test agent which inhibits binding ability of LRS to RagD or RagD GTPases and a method of reducing cell size compared to the control group comprising inhibiting expression of intracellular LRS. The method of the present invention provides novel method of regulating cell size and further the screening method of screening can be used in developing novel reagent for treatment of disease such as cancer.
