PRMT6 Proteins and Enzymes

PRMT6 severely impairs the function of HIV-1 Rev. PRMT6 is a protein arginine N-methyltransferase, and catalyzes the sequential transfer of a methyl group from S-adenosyl-L-methionine to the side chain nitrogens of arginine residues within proteins to form methylated arginine derivatives and S-adenosyl-L-homocysteine. Protein arginine methylation is a prevalent post-translational modification in eukaryotic cells that has been implicated in signal transduction, the metabolism of nascent pre-RNA, and the transcriptional activation processes. In addition, PRMT6 displays automethylation activity; it is the first PRMT to do so. PRMT6 has been shown to act as a restriction factor for HIV replication.
