1 We show that loss of the prolyl hydroxylase domain isoform 1 oxygen sensor in mice (PHD1KO) reduces muscle mass. Oxygen egl-9 family hypoxia-inducible factor 2 Mus musculus
2 PHD1KO muscles show impaired mTORC1 activation in response to leucine whereas mTORC1 activation by growth factors or eccentric contractions was preserved. Leucine egl-9 family hypoxia-inducible factor 2 Mus musculus
3 The ability of PHD1 to promote mTORC1 activity is independent of its hydroxylation activity but is caused by decreased protein content of the leucyl tRNA synthetase (LRS) leucine sensor. Leucine egl-9 family hypoxia-inducible factor 2 Mus musculus
