Proteins and proteomics

Catching tau in the act
Using a new proximity-labeling approach, researchers reveal how tangles of the brain-associated protein tau may disrupt RNA biology long before neurons die.

How copper delivery fuels bacterial respiration
Researchers identify the roles of several proteins in copper homeostasis in the aerobic bacterium Caulobacter vibrioides.

Revealing the glycoproteome of a cancer subtype
Researchers mapped the glycoproteome of extrahepatic cholangiocarcinoma and compared it to intrahepatic tumors. Differences in sugar modifications and immune cell content suggest new biomarkers and guide development of targeted immunotherapies.

Uncovering the mechanisms of a glycosylation disorder
Mutations in OGT, an enzyme that adds sugars to proteins, cause a rare neurological disorder. Using proteomics, researchers reveal how OGT interactions with TET proteins may trigger epigenetic changes and early neural defects.

Heat shock proteins as a promising breast cancer therapeutic
Researchers unveiled isoform-specific targets on heat shock protein 90 which may be beneficial in therapeutic development.

Optimized proteomic analysis of preserved biological tissue samples
Researchers have developed an optimized workflow for analyzing formalin-fixed paraffin-embedded tissue. This workflow provides an enhanced collection of unique proteins and phosphorylation sites for more detailed analysis of biological samples.

Blood proteomics reveals fungal infection signatures for faster diagnosis
Whole-blood proteomics identifies more than 3,000 host and 160 fungal proteins during cryptococcal infection, offering potential biomarkers for faster diagnosis and improved monitoring without invasive spinal taps.

When things get SAPpy: Novel insights into complement
Researchers have defined interactions between an innate immune protein and two of its known binding partners. They identified potential areas of crosstalk between the two binding interactions.

Glutathione pathway implicated in rare disease
Researchers found that glutathione metabolism plays a central role in the pathogenesis of rare disease methylmalonic aciduria using a novel multiomics approach.
