Increasing evidence supports that PRMTs exhibit the capacity to form higher-order oligomeric structures, but the structural basis of PRMT oligomerization and its functional consequence are elusive. Herein, we revealed for the first time different oligomeric structural forms of the predominant arginine methyltransferase PRMT1 using cryo-EM, which included tetramer (dimer of dimers), hexamer (trimer of dimers), octamer (tetramer of dimers), decamer (pentamer of dimers), and also helical filaments. Through a host of biochemical assays, we showed that PRMT1 methyltransferase activity was substantially enhanced as a result of the high-ordered oligomerization. High-ordered oligomerization increased the catalytic turnover and the multimethylation processivity of PRMT1. Presence of a catalytically dead PRMT1 mutant also enhanced the activity of WT PRMT1, pointing out a noncatalytic role of oligomerization. Structural modeling demonstrates that oligomerization enhances substrate retention at the PRMT1 surface through electrostatic force. Our studies offered key insights into PRMT1 oligomerization and established that oligomerization constitutes a novel molecular mechanism that positively regulates the enzymatic activity of PRMTs in biology. | |||||||||||||||||||||
