"Find protein structure of [target]" / "search PDB for [protein]" / "is there a crystal structure of [X]" / "[disease target] structures" / "CRISPR / kinase / GPCR structures" — text search the RCSB PDB (the global archive of experimentally-determined 3D protein/RNA/DNA structures). Returns matching PDB IDs you can pass to `structure` or `summary`. Use for structural biology, drug design, protein characterization.
