    "summary": "Structural work shows how one enzyme can switch between amino-acid sensing and mTORC1 activation through a reversible modification.",
    "body_text": "A KAIST team reports that methionyl-tRNA synthetase, or MARS1, responds to amino acids by releasing LARS1 and changing phosphorylation state, which lets LARS1 help activate the mTORC1 growth pathway. Structural and cell experiments trace how the same protein can alternate between its translation role and growth signaling. The mechanism offers a potential drug target, but this is basic molecular work rather than evidence of a cancer therapy.",
