Summary: Ion mobility enables spatial separation of ions in the gas phase, providing information about their size. The timsTOF Pro device can physically separate N-glycopeptides from nonmodified peptides and produce high-quality fragmentation spectra. This method allows for the effective selection of analytes of interest based on the clear cluster in the mobiologram formed by the glycan moieties enlarging the size of glycopeptides.

Summary: Most drugs target proteins, and determining the exact drug binding sites on proteins is crucial for understanding their effects. A strategy called PhosID-ABPP was developed to identify drug binding sites using immobilized metal-affinity chromatography and phosphonate affinity tags. This method successfully identified over 500 unique binding sites of the drug PF-06672131. PhosID-ABPP also revealed differences in binding sites between intact cells and cell lysates, and captured a previously elusive binding site on the epidermal growth factor receptor.

Summary: Native mass spectrometry is widely used for determining the mass of intact proteins and their biomolecular assemblies. However, it can be challenging for heterogeneous protein complexes. In 2012, an Orbitrap-based mass analyzer with extended mass range was introduced, enabling high-resolution mass spectra of large protein assemblies and single ion measurements. This led to the development of single-molecule Orbitrap-based charge detection mass spectrometry in 2020, which has opened doors for innovative research in various systems.

Summary: In this study, previously unrecognized cAMP nanodomains associated with beta-adrenergic stimulation were identified using an integrated phosphoproteomics approach and network analysis. The composition and function of one of these nanodomains were validated. The findings reveal a mechanism that explains the negative long-term clinical outcome observed in patients with heart failure treated with PDE3 inhibitors.

Summary: Knr4/Smi1 proteins are specific to the fungal kingdom and their deletion leads to hypersensitivity to anti-fungal agents and various stresses. Knr4 is involved in multiple signaling pathways in S. cerevisiae and interacts with several proteins in these pathways. Structural analysis revealed that Knr4 contains intrinsically disordered regions and a structured globular domain interrupted by a disordered loop.

Summary: The tricarboxylic acid cycle is a central pathway for energy production in eukaryotic cells and plays a key role in aerobic respiration across all life kingdoms. The 2-oxoglutarate dehydrogenase complex (OGDHC) is a crucial enzyme in this cycle, generating NADH by oxidatively decarboxylating 2-oxoglutarate to succinyl-CoA. We provide evidence that MRPS36 is an important component of eukaryotic OGDHC, supported by cross-linking mass spectrometry data and phylogenetic analyses. We propose that MRPS36 evolved as an E3 adaptor protein, functionally replacing the peripheral subunit-binding domain (PSBD) in eukaryotic E2o.

Summary: This study aimed to identify the interacting partners of CRISP2. The interactions of these binding partners were investigated under different conditions. The results suggest that CRISP2 may act as a scaffold for protein complex formation and dissociation to ensure the correct positioning of proteins required for the acrosome reaction and zona pellucida penetration.

Summary: In this study, it is found that by modifying the structure of monoclonal antibodies (mAbs), the immune protection and bactericidal effect against Streptococcus pneumoniae can be improved. The modified mAbs effectively activate the complement system and recruit complement component C1 for bacterial clearance, enhancing the antibacterial activity against various serotypes of pneumococci. This study provides an important proof of concept for the future development of antibody therapies against encapsulated bacteria.

Summary: Currently available enzyme replacement therapies for lysosomal storage diseases are limited in their effectiveness due to short circulation times and suboptimal biodistribution of the therapeutic enzymes. Researchers have engineered Chinese hamster ovary (CHO) cells to produce glycoengineered enzymes, which have improved circulation time and biodistribution. This glycoengineering approach, known as Long-Acting-GlycoDesign (LAGD), may be widely applicable to lysosomal replacement enzymes to improve their circulatory stability and therapeutic efficacy.

Summary: The dysregulation of immune checkpoint molecules allows cancer cells to escape immune destruction. CD58, an important costimulatory ligand, is found to be positively regulated by CMTM6, which also interacts with PD-L1. The presence of CMTM6 and CD58 on tumor cells significantly affects T cell-tumor interactions and the response to PD-L1-PD-1 blockade.

Summary: The mammalian respiratory chain complexes CI, CIII2, and CIV form a stable assembly called the respirasome, which is critical for cellular bioenergetics. By studying knockin mice with decreased levels of respirasomes, researchers found that high levels of respirasomes are dispensable for maintaining bioenergetics and physiology in mice. However, the alternate functions of respirasomes, such as regulating protein stability and preventing age-associated protein aggregation, need further investigation.

Summary: Mitochondria, packed with proteins, play important roles in various cellular processes. While many mitochondrial protein complexes have been identified, some protein-protein interactions remain elusive. Cross-linking mass spectrometry (XL-MS) has proven to be a valuable tool for the in-depth characterization of these interactions. In this article, experimental strategies for the analysis of proteome-wide protein-protein interactions in mitochondria using XL-MS are highlighted, along with recent technological advances that can further enhance the in situ characterization of these interactions.

Summary: We monitored the changes in bovine milk IgG over a 28-day period after calving, finding that IgG accounts for over 50% of protein content in colostrum but less than 3% in mature milk. The N-glycosylation profile of bovine milk IgG was found to be highly heterogeneous with over 40 glycoforms, and this profile changed significantly during lactation. We also identified the presence of IgG3 subtype in bovine milk, alongside IgG1 and IgG2. These findings are important for understanding calf's immune development and the nutritional value of bovine milk.

Summary: The most abundant immunoglobulin in the human body is IgA and it is found in high concentrations in mucosal lining and biofluids like milk. The structure and clonal repertoire of IgA1-containing molecular assemblies were analyzed using mass spectrometry-based approach in serum and milk from three donors. The results showed that serum IgA1 consists of two distinct structural populations, monomeric IgA1 and dimeric J-chain coupled IgA1, while IgA1 in milk is present only as secretory IgA (SIgA) with various assemblies. The IgA1-Fab repertoires in serum and milk were also found to be different.
