Summary
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 unveil that Cobl is controlled by arginine methylation. Coprecipitations, coimmunoprecipitations, cellular reconstitutions and in vitro reconstitutions demonstrated that Cobl associates with the protein arginine methyltransferase PRMT2 in an SH3 domain-dependent manner and that this promotes methylation of Cobl’s actin nucleating C terminal domain. Consistently, PRMT2 phenocopied Cobl functions in both gain- and loss-of-function studies, both PRMT2- and Cobl-promoted dendritogenesis relied on methylation and PRMT2 required functionality of its catalytic and its SH3 domain. Furthermore, Cobl-mediated dendritic arborization required PRMT2, complex formation with PRMT2 and PRMT2’s catalytic activity. Mechanistic studies unveiled that Cobl methylation is key for Cobl’s actin binding. Therefore, arginine methylation is a regulatory mechanism reaching beyond controlling nuclear processes. It also controls a major, cytosolic, cytoskeletal component shaping neuronal cells.
