catalytic activity:L-arginyl-tRNA + protein = tRNA + L-arginyl-protein.,caution:It is uncertain whether Met-1 or Met-37 is the initiator.,function:Involved in the post-translational conjugation of arginine to the N-terminal aspartate or glutamate of a protein. This arginylation is required for degradation of the protein via the ubiquitin pathway. Does not arginylate cysteine residues.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the R-transferase family.,subunit:Monomer .,
