ICF45 Adds a GMP to the 5'-end of tRNA(His) after transcription and RNase P cleavage. This step is essential for proper recognition of the tRNA and for the fidelity of protein synthesis. Belongs to the tRNA(His) guanylyltransferase family. Expressed in many tissues. Note: This description may include information from UniProtKB.
