Researchers create protein interaction map linking high-risk genes to profound autism

Researchers from UC San Francisco assembled a molecular atlas of roughly 1,800 protein interactions derived from proteins encoded by high-impact autism genes. The study combined experimental pull-down assays in cultured cells with AI-driven structural predictions from AlphaFold to pinpoint direct contacts. By introducing patient-derived mutations, the team observed how specific interactions were disrupted, revealing convergence on pathways governing synapse formation and neuronal timing.

Experts outside the project called the resource unprecedented and likely to accelerate drug development. Autism advocacy leaders expressed optimism that targeting these common protein networks could streamline therapies for profound autism. The work follows a recent $46 million grant from the Aligning Research to Impact Autism initiative, funded by Sergey Brin, to further explore therapeutic avenues.
