Gene Synthesis> | Briefly, plasmids containing the RIM4 CDS with all serines and threonines mutated to alanine (pLB90) or glutamic acid (pLB119) (synthesized by Genscript) and the HIS3 selectable marker were used as a template to generate PCR products which were transformed into the RIM4 locus. | Get A Quote |
Amyloids are fibrous protein assemblies that are often described as irreversible and intrinsically pathogenic. However, yeast cells employ amyloid-like assemblies of the RNA-binding protein Rim4 to control translation during meiosis. Here, we show that multi-site phosphorylation of Rim4 is critical for its regulated disassembly and degradation and that failure to clear Rim4 assemblies interferes with meiotic progression. Furthermore, we identify the protein kinase Ime2 to bring about Rim4 clearance via phosphorylation of Rim4's intrinsically disordered region. Rim4 phosphorylation leads to reversal of its amyloid-like properties and degradation by the proteasome. Our data support a model in which a thresh... More
