Article Synopsis
  • - Arabidopsis ecotype Col-0 has over 100 proteins encoded by its plastid and mitochondrial genomes, but data inconsistencies exist in public databases regarding these proteins' identifiers.
  • - The study focused on RNA editing effects on protein synthesis, identifying 452 predicted editing sites and successfully detecting 167 of these at the protein level from a massive dataset of MS spectra.
  • - Key findings show that major RNA editing sites are critical for protein stability, with heavily edited proteins often found in an edited form, highlighting the importance of RNA editing in protein function.

Unlabelled: Young workers in Spain face the unprecedented impact of the Great Recession and the COVID-19 crisis in short sequence. Moreover, they have also experienced a deterioration in their employment and earnings over the last three decades. In this paper, we document this evolution and adopt a longitudinal approach to show that employment and earnings losses suffered by young workers during recessions are not made up in the subsequent expansions.

In the chloroplast, organelle zinc finger 1 (OZ1) is a RanBP2-type zinc finger (Znf) protein required for many RNA editing events, a process by which specific cytosines are enzymatically converted to uracils as a correction mechanism for missense mutations in the organelle genomes. RNA editing is carried out by a large multi-protein complex called the 'editosome' that contains members of the pentatricopeptide repeat (PPR) protein family, the RNA editing factor interacting protein (also known as MORF) family and the organelle RNA-recognition motif (ORRM) family, in addition to OZ1. OZ1 is an 82-kDa protein with distinct domains, including a pair of Znf domains and a unique C-terminal region.

The RanBP2 zinc finger (Znf) domain is a prevalent domain that mediates protein interaction and RNA binding. In Arabidopsis, a clade of four RanBP2 Znf-containing proteins, named the Organelle Zinc (OZ) finger family, are known or predicted to be targeted to either the mitochondria or the plastids. Previously we reported that OZ1 is absolutely required for the editing of 14 sites in chloroplasts.

OZ1, an RNA editing factor that controls the editing of 14 cytidine targets in Arabidopsis chloroplasts, contains two RanBP2-type zinc finger (Znf) domains. The RanBP2 Znf is a C4-type member of the broader zinc finger family with unique functions and an unusually diverse distribution in plants. The domain can mediate interactions with proteins or RNA and appears in protein types such as proteases, RNA editing factors, and chromatin modifiers; however, few characterized Arabidopsis proteins containing RanBP2 Znfs have been studied specifically with the domain in mind.
