  Evaluation Summary:

  HCV is unique in its glycoprotein structure, complex receptor usage and its unusual persistence for a (+)RNA virus. This is a well done study that explains a number of observations regarding receptor usage and how HCV may evade antibody control via HVR1 due to its disordered nature, enable mutation to continually evade antibody responses. This manuscript should be of substantial interest to those in the fields of virus entry, vaccination against human viruses, and the study of how intrinsically disordered regions can play regulatory roles.

  Evaluation Summary:

  This work characterizes chromatin compaction in quiescent yeast cells and its role in the repression of gene expression. The authors' findings that chromatin compaction via heterogeneous interactions between nucleosomes directly contributes to transcriptional repression provides a useful conceptual paradigm for studies of quiescence in other organisms.

  Evaluation Summary:

  Gene regulation triggered by recognising N6-methyladenosine (m6A) by RNA-binding proteins emerged as a fundamental process for development and adaptation in most eukaryotes. This paper is of interest to scientists within the field of post-transcriptional gene regulation and RNA biology. In a deep and thorough analysis, the authors resolved previously contradictory reports of sequence motifs associated with methylation sites in messenger RNAs and shed light on the proteins that recognise this modification.

  Evaluation Summary:

  Post-transcriptional gene regulation mediated by YTH proteins that bind N6-methyladenosine (m6A) in mRNA is a pathway that has emerged of importance in eukaryotic biology. This paper focuses on two evolutionarily close proteins of this family, ETC2 and ETC3 to find redundant, specific and divergent functions. The authors addressed previously contradictory reports regarding the subcellular location of these proteins. The paper is of general interest to scientists within the field of post-transcriptional gene regulation and RNA biology and is not limited to the plant research community. This will advance our understanding of mRNA methylation and its role in plant biology.

  Evaluation Summary:

  This work examines how METTLL18-mediated RPL3 histidine methylation on 245 position regulates translation elongation and protects cells from cellular aggregation of Tyr-rich proteins. The study hints at the existence of a "ribosome code" and how posttranslational modification of ribosomal proteins could affect translation.
