11. Structural multiplicity usually underlies functional multiplicity of protein complexes following a fuzzy logic. 12. This protein complex likely helps regulate the transmission of sound waves. 13. This set of protein complexes is critical for down-regulating activated cell surface receptors. 14. ATP synthase is a massive protein complex with a mushroom-like shape. 15. This protein forms a 103 kDa protein complex with unidentified proteins. 16. This protein is a subunit of the protein complex that consists of MCM2-7. 17. The product of this gene is an epsilon subunit of coatomer protein complex . 18. Individual proteins can participate in the formation of a variety of different protein complexes . 19. The Affinity purification and subsequent mass spectrometry is suited to identify a protein complex . 20. COMPLEAT may be used to analyze high-throughput datasets where protein complex information is relevant.
