Can we model protein structures from their protein sequences?

14 Comparative Protein Structure Modelling
Why do we need automated expert systems for comparative protein modelling? Too many new sequences, too many new structures Objectivity and Reproducibility: remove individual human bias; predictable reliability of results Improve methods and algorithms Easy access for “end users”

24 Evaluation of Model Accuracy

25 Evaluation of model accuracy
“... a model must be wrong, in some respects -- else it would be the thing itself. The trick is to see ... where it is right.” Henry A. Bent "Uses (and Abuses) of Models in Teaching Chemistry," J. Chem. Ed , 774. SIV Model based on: 1BL3 (C) HIV-1 Integrase core domain Experimental structure: 1C6V (C) SIV Integrase core domain Seq. Identity: 61 %

28 Evaluation of Automated protein structure prediction
Evaluation of 246 weekly PDB releases (20'108 models) The analysis of ~1 year of models for all PDB released structures is necessary for a statistically relevant comparison of modelling methods. [ Data source: EVA-CM ]

29 Evaluation of Automated protein structure prediction
Evaluation of 246 weekly PDB releases (20'108 models) SWISS-MODEL has the lowest cumulative average global RMSD of the servers in the comparison. [ Data source: EVA-CM ]

30 Evaluation of Automated protein structure prediction
Evaluation of 246 weekly PDB releases (20'108 models) The lower RMSD of SWISS-MODEL is related to a lower coverage in sequence space. Chain Difficulty: Ranges from 0 (easiest) to 100 (most difficult). The difficulty level is defined as the percentage of missaligned residues between an optimal structural superimposition alignment and a pairwise sequence alignment method. If the sequence alignment is identical to the structural alignment, the difficulty is 0. If there is no similarity in any structural alignment (CE), the difficulty is 100. [ Data source: EVA-CM ]

32 Applications of comparative modelling
Possible applications of comparative models depend on the expected accuracy. (Kopp & Schwede, Pharmacogenomics, 2004 )

33 Application Examples

34 Rational design of Functional Mutations
Applications: Structural Assessment of Sequence Variations Comparative modeling allows for detailed structure-based assessment of sequence variations. Mutations, ns-cSNPs, alternative splicing, iso-forms and other sequence variations may be responsible for functional variations and involved in rare inherited diseases, individual differences in drug response, and susceptibility for common diseases. (Wattenhofer, et. al. J. Mol. Med ) Rational design of Functional Mutations Comparative modeling allows for designing specific site directed mutations to study functional role of individual residues or structural features. Example: Design of partial and complete deletion mutations of the plug domain of Sec61p to study its functional role. Conclusion: The plug domain of Sec61p is non-essential, but influences topogenesis and Sec61 assembly. Junne, Schwede, Goder & Spiess (2006) Molecular Cell, in press

35 Application: Models in structure based drug discovery
Can homology models be used in structure based drug discovery when no experimental protein structures are available? How do errors and inaccuracies of the homology models affect the subsequent molecular modeling of protein-ligand interaction?

37 Summary and Outlook

38 Summary and outlook Today's Bioinformatics view is still largely (DNA)- sequence centric. Understanding macromolecular function in detail requires knowledge of its 3D structure. 10 years ago, for the vast the majority of proteins no information about its 3-dimensional structure was available. Today, structural genomics and comparative modelling are complementing each other in exploring the structural space. Within the next decade, 3D information will become available for the majority of all globular protein domains. > 90 % of this structural information will be based on comparative models. SWISS-MODEL aims at providing a fully integrated protein-centric view of all available structural information on a given protein.
