Rational design of disordered proteins for sequence-function investigation.

Rational design of IDRs with GOOSE enables exploration of sequence-function relationships in disordered proteins, revealing key insights into their cellular roles.

• Why it matters: Understanding and designing IDRs is crucial because they are widespread and perform essential functions despite lacking stable structures, yet current design methods are limited.
• What they did: The authors developed GOOSE, a computational framework that allows the design and testing of thousands of IDR sequences to study how sequence properties affect their structure and function.
• The result: This approach uncovered how sequence influences IDR behavior, enabling the creation of proteins that respond to cellular changes, self-assemble, recruit specific partners, and protect cells, advancing functional protein design.
