Multi-protein assemblies

Many PDB files contain complexes in which a particular protein is interacting with a different protein in what are called multi-protein assemblies or multi-protein complexes. These interactions, if biologically relevant, can be immensely insightful in shedding light on cellular and extracellular processes.

ExamplesExamples

• Ribosome
• Human Follicle-Stimulating Hormone Complexed with its Receptor
• Platelet-receptor glycoprotein Ib alpha bound to the von Willebrand Factor A1 Domain
