Biochem/physiol Actions

Protein arginine N-methyltransferases (PRMTs) are involved in post-translational modification implicated in protein trafficking, signal transduction, and transcriptional regulation. AMI-1 does not inhibit lysine methyltransferase activity and does not interact with S-adenosylmethionine (AdoMet), unlike most methyltransferase inhibitors which compete for the AdoMet binding site. AMI-1 can modulate nuclear receptor-regulated transcription from estrogen and androgen response elements; and is a HIV-1 reverse transcriptase inhibitor. AMI-1 is a potent antagonist of NADPH-oxidase-derived superoxide production, but acts as a direct antioxidant rather than indirectly through methyltransferase inhibition.

The complex architecture of neuronal networks in the brain requires tight control of the actin cytoskeleton. The actin nucleator Cobl is critical for neuronal morphogenesis. Here we reveal that Cobl is controlled by arginine methylation. Coprecipitations, coimmunoprecipitations, cellular reconstitutions, and in vitro
