  This important study reports on a basis for neurabin-mediated specification of substrate choice by protein phosphatase-1. The data from the comprehensive approach using structural, biochemical, and computational methods are compelling. This paper is broadly relevant to those investigating various cellular signaling cascades that entail phosphorylation as the main mechanism.

SFSWAP is a negative regulator of OGT intron detention and global pre-mRNA splicing

• Curated by eLife

  eLife Assessment

  This study provides fundamental insights into the regulation of a retained intron in the mRNA coding for OGT, a process known to be regulated by the O-GlcNAc cycling system, and highlights the functional role of the splicing regulator SFSWAP. The evidence supporting the claims of the authors is convincing; the authors performed an elegant state-of-the-art CRISPR knockout strategy and sophisticated bioinformatic analysis to identify SFSWAP as a negative regulator of alternative splicing. The work will be of interest to researchers in the fields of splicing and glycobiology.

  eLife Assessment

  This study is a valuable observation that deals with the toxic effects of an intermediary in lipid degradation [trans-2-hexadecenal (t-2-hex)] in yeast through modification of mitochondrial protein import via the TOM complex. We find that the claim that the TOM complex is a main target of t-2-hex are supported by solid evidence, however the molecular mechanism remains unclear allowing multiple interpretation. Despite the shortcomings, this study is inspiring for researchers from the organellar, protein trafficking and lipid field and serves as a starting point to further precise and mechanistic analyses of the phenomenon.
