Cdc123-mediated assembly of the translation factor eIF2: mechanism and significance (B10)

• Subject Area: Biochemistry
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 185476941

To define the mechanism by which the ATP-grasp protein Cdc123 assembles the hetero-trimeric eIF2 complex we will continue the genetic and biochemical characterization of yeast Cdc123 mutants, employ advanced NMR methods to study protein associations and dynamics, search for a covalent eIF2 modification by SILAC mass spectrometry, and study the in vivo association of eIF2 with the initiator tRNA by RNA immunoprecipitation. To understand the anti-proliferative effect associated with chronic dysfunction of Cdc123 and eIF2, we will profile gene expression, specifically mRNA translation, by RNA-sequencing based methods.
