Citation | Journal: J Biol Chem / Year: 2025Title: Substrate adaptors are flexible tethering modules that enhance substrate methylation by the arginine methyltransferase PRMT5. Authors: Cyrus Y Jin / Moritz Hunkeler / Kathleen M Mulvaney / William R Sellers / Eric S Fischer / ![]() Abstract: Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine marks. PRMT5 uses substrate adaptors such ...Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine marks. PRMT5 uses substrate adaptors such as pICln, RIOK1, and COPR5 to recruit and methylate a wide range of substrates. Although the substrate adaptors play important roles in substrate recognition, how they direct PRMT5 activity towards specific substrates remains incompletely understood. Using biochemistry and cryogenic electron microscopy, we show that these adaptors compete for the same binding site on PRMT5. We find that substrate adaptor and substrate complexes are bound to PRMT5 through two peptide motifs, enabling these adaptors to act as flexible tethering modules to enhance substrate methylation. Taken together, our results shed structural and mechanistic light on the PRMT5 substrate adaptor function and the biochemical nature of PRMT5 interactors. #1: Journal: Acta Crystallogr D Struct Biol / Year: 2019 Title: Macromolecular structure determination using X-rays, neutrons and electrons: recent developments in Phenix.

The overall structure-solution workflow is similar for these techniques, but nuances exist because the properties of the reduced experimental data are different. Software tools for structure determination should therefore be tailored for each method. Phenix is a comprehensive software package for macromolecular structure determination that handles data from any of these techniques. Tasks performed with Phenix include data-quality assessment, map improvement, model building, the validation/rebuilding/refinement cycle and deposition. Each tool caters to the type of experimental data. The design of Phenix emphasizes the automation of procedures, where possible, to minimize repetitive and time-consuming manual tasks, while default parameters are chosen to encourage best practice. A graphical user interface provides access to many command-line features of Phenix and streamlines the transition between programs, project tracking and re-running of previous tasks. | ||||||

They are numbered such that they end with ARG-114. However, this region could actually be any stretch of GRGRGR between residues 97 and 114 (or in the case of chain N, any stretch of RGRGR between residues 98 and 114). | |
