# A Claude-run search across 15 billion predicted proteins finds a bacteriophage protein that assembles into vault-like particles

Anthropic's biology team says cryo-electron microscopy confirmed a 96-copy shell of about 9.5 megadaltons, while the biological function of vault particles is still unknown.

Anthropic published a research account on November 4 of a structural-biology project in which Claude directed much of the work. Vaults are large barrel-shaped protein shells found in many eukaryotic cells, and coverage describes their purpo…
