Arginine methylation controls the strength of γc-family cytokine signaling in T cell maintenance

The methylation of arginine residues in proteins is a post-translational modification that contributes to a wide range of biological processes. Many cytokines involved in T cell development and activation utilize the common cytokine receptor γ-chain (γc) and the kinase JAK3 for signal transduction, but the regulatory mechanism that underlies the expression of these factors remains unclear. Here we found that the arginine methyltransferase PRMT5...
