A comprehensive whole cell proteomic map describing expression time courses of >6,500 viral and cellular proteins during HIV infection identifies Vif-dependent antagonism of key cellular phosphatase PP2A.
A detailed analysis of protein abundance and phosphorylation changes across mitotic subphases and interphase in asynchronously growing human cells has been enabled by combining FACS with quantitative MS-based proteomics.
Mass spectrometry exposes a post-transcriptionally regulated reduction in protein diversity in hematopoietic stem cells, including a lack of detectable Dnmt3a protein levels despite mRNA levels comparable to progenitors.
Zeno SWATH MS, a novel data-independent acquisition technique in proteomics, which by facilitating sensitive detection in high-throughput experiments with low sample amounts, mitigates current bottlenecks of high-throughput proteomics.
Quantitative proteomic analysis shows that recessive Ryr1 mutations not only decrease the content of RyR1 protein in muscle, but also affect the content of many other proteins involved in a variety of biological processes.

Enzyme tethering of promiscuous biotinylators to the cell surface allows for more rapid and efficient comparative surface proteomic analysis of cells and extracellular vesicles.
Deep and comprehensive proteomic resource of human intervertebral disc at high spatial resolution with a methodological flow reveals new insights in disc homeostasis and degeneration.
