Systematic conformation-to-phenotype mapping via limited deep-sequencing of proteins

The paper develops a method to map protein conformations to phenotypes by systematically analyzing disulfide bonds in proteins.

Molecular physiology of pumiliotoxin sequestration in a poison frog

This study investigates how the Dyeing poison frog metabolizes pumiliotoxin into a more potent alkaloid and identifies gene expression changes and potential metabolic enzymes involved.

Microstructures amplify carotenoid plumage signals in colorful tanagers

The paper quantifies carotenoid signals in tanagers, showing males have microstructures that amplify color appearance, challenging the idea that carotenoids alone explain plumage honesty.

Rapid toxin sequestration modifies poison frog physiology

This study shows poison frogs rapidly accumulate toxins, altering protein abundance in immune response and small molecule transport across tissues.

Land use impacts poison frog chemical defenses through changes in leaf litter ant communities

This study links land use changes to poison frog chemical defenses by showing habitat fragmentation alters leaf litter ant communities, which in turn affects frog diet and alkaloid profiles.

Molecular physiology of chemical defenses in a poison frog

The paper investigates how alkaloid sequestration affects gene expression and protein abundance in poison frogs, identifying transport proteins and saxiphilin as potential mediators of toxin accumulation.

Seasonal changes in diet and toxicity in the Climbing Mantella frog (Mantella laevigata)

This study examines how seasonal environmental changes affect the diet and toxin profiles of Climbing Mantella frogs, finding seasonal differences in diet composition and toxin abundance.

Catalysis of cataract-associated human γD crystallin aggregation via dynamic disulfide exchange

The paper shows wild-type human γD crystallin catalyzes aggregation of its W42Q variant through disulfide bond transfer, revealing a redox mechanism relevant to protein aggregation in oxidizing environments.
