Part of the Stack; How Does a Protein Know its Place?

Parsons et al. successfully separate early to late Golgi cisternae to reveal the sequential localization of resident proteins and the sequence features that guide transmembrane proteins within the Golgi stack. Plant Cell https://doi.org/10.1105/tpc.19.00081 By Harriet T. Parsons (University of Cambridge)…

Review: N-degron pathway-mediated proteostasis in stress physiology (Annu Rev Plant Biol)

The rate of most biological processes is ultimately determined by protein activity levels, which of course are determined by rate of degradation or inactivation as well as production. Dissmeyer reviews the Cys/Arg branch of the N-degron pathway (previously called the N-end rule pathway) that contributes…

MapMan4: A refined protein classification and annotation framework applicable to multi-omics data analysis (Mol Plant)

Revolutions in omics technologies have rapidly increased the number of plant genomes, transcriptomes and proteomes available. However, protein sequences need to be assigned a biological function to provide useful insights for comparative genomics and transcriptomics. Here, Schwacke et al present MapMan4,…

Updates on Resources, Software Tools, and Databases for Plant Proteomics in 2016–2017 ($) (Electrophoresis)

Proteomics, like metabolomics research, depends on the mass-spectrometry tools.  Data processing, protein annotation, statistical and data analysis, as well as visualization are often the hurdles in obtaining meaningful biological insights from high throughput datasets. To this end, the author has summarized…

APOPLASTP: prediction of effectors and plant proteins in the apoplast using machine learning ($)

The apoplast represents a highly interactive site for intercellular communication and transport in plant-microbe interaction, that determines whether a pathogen can successfully overcome the early stages of plant defense. This site is also a battleground for an important class of apoplastic effectors…
