揭示了KICSTOR与GATOR1组装成新月形溶酶体复合物调控mTORC1的机制,发现SAMTOR以S-腺苷甲硫氨酸不兼容构象结合KICSTOR,建立甲硫氨酸感知与mTORC1调控的耦合关系。

📝 英文原版摘要

This study reveals how KICSTOR and GATOR1 assemble into a crescent-shaped lysosomal complex that regulates mTORC1 during amino acid starvation and how SAMTOR binds KICSTOR in an S-adenosylmethionine-incompatible conformation to couple methionine sensing to mTORC1 regulation.
