Phosphorylation of human TRM9L integrates multiple stress-signaling pathways for tumor growth suppression

Abstract excerpt

The human transfer RNA methyltransferase 9-like gene (TRM9L, also known as KIAA1456) encodes a negative regulator of tumor growth that is frequently silenced in many forms of cancer. While TRM9L can inhibit tumor cell growth in vivo, the molecular mechanisms underlying the tumor inhibition activity of TRM9L are unknown. We show that oxidative stress induces the rapid and dose-dependent phosphorylation of TRM9L...
