The paper reveals how phosphorylation of SMO in the Hedgehog pathway stabilizes a conformation that inhibits PKA-C, providing a structural mechanism for noncanonical GPCR signaling.

This paper introduces a scalable proximity proteomics pipeline that improves reproducibility and throughput in biotinylation-based spatial proteomics.

The paper constructs a PPI network of 100 high-confidence ASD genes, identifies novel interactions, and uses AlphaFold-Multimer to prioritize variants for functional validation in organoids.

The paper systematically analyzes proteomic and genomic data of SARS-CoV-2 variants to identify how mutations affect viral gene expression, host interactions, and immune evasion.

The paper identifies novel regulators of mu opioid receptor signaling and trafficking using proximity labeling and proteomics.

The paper investigates how the GTPase Ran/Gsp1 achieves functional multi-specificity through biophysical and genetic perturbations, revealing that its effects are linked to kinetic parameters of the switch cycle rather than direct interaction sites.

Affinity-purification mass spectrometry of 26 SARS-CoV-2 proteins in HEK293T cells yields 332 high-confidence host interactions and 67 druggable human proteins with known compounds.

The paper identifies non-catalytic phenotypes in yeast enzymes, suggesting moonlighting activities beyond their annotated functions.
