Acanthamoeba ATP synthase structure reveals the TCA cycle is tethered to OXPHOS

SUMMARY Oxidative phosphorylation (OXPHOS) is a key metabolic process that couples redox energy to ATP production. While some core OXPHOS complex subunits are found across all domains of life, many have diverged or expanded across evolution—as seen in the protozoan pathogen Acanthamoeba castellanii. By integrating cryo...

A high-confidence inventory of the proteins in the mitochondrion-related organelle of Giardia

SUMMARY Giardia lamblia is a microaerophilic protozoan parasite that infects nearly 280 million people worldwide each year. Giardia lacks a mitochondrial genome and mitochondrial enzymes for oxidative phosphorylation. However, it retains mitochondrion-related organelles (MROs) that house an iron-sulfur cluster (ISC) as...

Conserved and divergent mitochondrial assemblies in kinetoplastid parasites

SUMMARY The mitochondrial proteomes of Leishmania tarentolae and Trypanosoma brucei contain ~1,700 proteins, most of which lack homologs in higher eukaryotes. Here, we integrate complexome profiling and cryo-electron microscopy to define conserved and lineage-specific macromolecular assemblies that support mitochondria...

Scaling measurements of peptide-HLA complex stability using user-defined libraries and mass spectrometry 2310029

A high-throughput assay to quantify stability of thousands of user-defined pHLA produced in E. coli and generated customizable pHLA stability datasets which show how peptide sequence motifs affect pHLA stability, and may be helpful for improving the authors' mechanistic understanding of pHLA stability.

Latent effector T cells mediate immunotherapy responses in the bone marrow microenvironment.

TFiT (tumor-reactive features in T cells), a transcriptional classifier that identifies tumor-reactive T cells and stratifies immunotherapy, but not chemotherapy, response across independent MM and AML cohorts, supporting its specificity for T cell-mediated tumor control.

Seed-Guided De Novo Design Expands the Structural Diversity of Antitoxin Protein Binders

These results establish motif scaffolding of surface-complementing seeds as an effective strategy for overcoming current limitations of de novo generative models, enabling the design of proteins that can engage challenging interface sites.
