  Rad23 escapes degradation because it lacks a proteasome initiation region

  Rad23 accompanies ubiquitinated substrates to the proteasome for destruction but manages to avoid degradation. In this study, Fishbainet al.show that Rad23 escapes because it lacks an effective initiation region; therefore, the proteasome is unable to engage the protein and unfold it.

  C-terminal UBA domains protect ubiquitin receptors by preventing initiation of protein degradation

  Rad23 and Dsk2 bind polyubiquitylated proteins and escort them to the proteasome for destruction. In this study, Heinenet al.investigate the molecular mechanisms that protect the C-terminal UBA domains of Rad23 and Dsk2 from proteasomal destruction.

  Systems-wide temporal proteomic profiling in glucose-starved Bacillus subtilis

  Identifying the transcripts and proteins that fluctuate in response to stimuli provides important information for understanding cell physiology. In this study, 52% of theBacillus subtilispredicted proteome is identified following glucose starvation, revealing further insight into protein dynamics at a global scale.
