ATE1 and non-small cell lung carcinoma: Additionally, the ratio of oxidative stress-induced exosome cargoes with increased or decreased expression upon genetic depletion of ATE1 was essentially 1-to-1 (Figures S3A–S3C), indicating that Nt-arginylation is a determinant for proteins included and excluded in oxidative stress-induced NSCLC-derived exosomes.
