Proteomics-Based Insights Into the SARS-CoV-2–Mediated COVID-19 Pandemic: A Review of the First Year of ResearchIn Brief SARS-CoV-2, the betacoronavirus that caused the COVID-19 pandemic, became a major source of human disease and death in 2020. The fundamental constituents of a virus being its genome and proteome, characterizing the proteome is essential to understanding its biology. In this review article, we survey the proteomics literature from the first year of the COVID-19 pandemic, including protein–protein interaction studies, post-translational modification studies, and work using proteomics technologies to probe host response, which collectively inform efforts to ameliorate the pandemic.
Calculating Glycoprotein Similarities From Mass Spectrometric DataIn Brief To understand the roles of glycoproteins in biological processes, it is necessary to quantify the changes that occur to glycosylation at individual sites and to the whole molecule. That glycoprotein glycosylation is inherently heterogeneous means that the distribution of glycoforms at each glycosite must be quantified in order to inform calculation of molecular similarities. We review analytical and statistical methods for determining glycoprotein molecular similarities from glycoproteomics data.
