[ccp4bb] CASP11 Meeting early registration dealine tomorow Friday, September 5
CASP11: Critical Assessment of Structure Prediction Date: December 7-10, 2014 Venue: Paraiso Lindo, Puerto Juarez, Riviera Maya, Mexico Connecting Airport: Cancun, Mexico The CASP meetings focus on assessing the state-of-the-art in protein structure modeling. Results of the 11th blind structure prediction experiment will be discussed at the upcoming meeting on December 7-10, 2014. In this round, the prediction assessment will pay increased attention to the usefulness of models in real life applications rather than only their numerical accuracy. New modeling categories include the use of sparse experimental data (NMR and cross-linking) in improving the reliability of models. Protein structure modelers and biologists interested in applying structural information in their research are encouraged to attend.

[ccp4bb] Workshop on the PDBx/mmCIF Data Exchange Format For Structural Biology (October 22, 2013) and PSI Workshop on Theoretical Model Archiving and Validation (October 21, 2013)
*Workshop on the PDBx/mmCIF Data Exchange Format For Structural Biology* Center For Integrative Proteomics Research Rutgers, The State University of New Jersey Tuesday October 22, 2013 http://www.proteinmodelportal.org/workshop-2013/ The wwPDB has established PDBx/mmCIF as the new standard format for data exchange and archiving in structural biology (http://www.wwpdb.org/news/news_2013.html#22-May-2013). To help facilitate the transition from PDB to PDBx/mmCIF format the wwPDB is organizing a programmer's workshop describing the content and organization of PDBx/mmCIF data, and the available software tools and libraries supporting PDBx/mmCIF (C/C++, Java, and Python). The workshop will be held on Tuesday, October 22, 2013 at Rutgers, The State University of New Jersey (in conjunction with a PSI Workshop on Theoretical Model Archiving and Validation to be held Monday, October 21, 2013): Starting at 9am, the morning session will include presentations from: Paul Adams (Phenix), David Case (AMBER), Tom Goddard (UCSF Chimera), Robert Hanson (JMol), Eugene Krissinel (CCP4/mmdb), Andreas Prilic (BioJava), John Westbrook (RCSB PDB). The afternoon session will offer an opportunity to work hands-on with the presenters and developers in the areas of structural biology and molecular modeling to learn application details and to discuss successful approaches and experiences in adapting software to support PDBx/mmCIF. In addition, the workshop will include a discussion of PDBx/mmCIF extensions required to represent molecular modeling specific information. There is no registration fee, but online registration is required (registration Deadline is October 4).

[ccp4bb] CASP10: Call for structure prediction targets
Dear colleagues, This is a follow up to our earlier message, requesting prediction targets for CASP10. First THANK YOU to those who came forward with targets -- really much appreciated, and has helped get this CASP off to a great start. We now have over 70 targets released. Second, please send more targets! There is still a month of the prediction season to run, and the first batch of targets is all used up. The details of what is needed and so on are below -- just like in the earlier message. Again, thanks to the structural biology community for all your help, in this and previous CASPs (1): /CASP10 organizers: Torsten Schwede, Andriy Kryshtafovych, Anna Tramontano, Krzysztof Fidelis and John Moult./ *The specifics:* We need all sorts of targets but in particular: 1. (More than ever) novel folds and membrane protein targets -- even with the extended collection season provided by CASP ROLL (http://predictioncenter.org/casprol/index.cgi) there will be still a shortage. This round there are some interesting methods developments for ab initio modeling, and it is important to be able to decisively evaluate their effectiveness. 2. A diversity of comparative modeling targets. Cases where the there is fairly high sequence identity (30-50%) between the target structure and an available template are valuable for testing the degree to which model accuracy can approach that of experiment, particularly in functionally critical regions. Cases with lower sequence identity to template, right down to undetectable, are valuable for testing the ability of the methods to detect remote homologs, to overcome challenging alignment difficulties, to make use of multiple templates, and to build regions of the structure not obviously available from a template. 3. Targets containing significant amounts of disordered structure, so as to test the ability of methods to identify these regions. Disorder identified by absence of density in crystallography is current the main source and very useful, but its important to have cases where the nature of the disorder has been established by other means, such as NMR. 4. Some targets will also be used to test methods of structure refinement. In these cases, the best model received for a target will be released to the refinement community, who will subsequently submit new models. This too is an area where there have been some exciting developments in the last year, so we are hoping for significant progress. Refinement targets are selected based on the nature of the errors in the initial models. Because of the extended process, these targets need to be available for longer before release of the experimental structure. The time table is similar to other CASPs: The prediction season opened at the beginning of May, and will run until the end of July. We are releasing targets continuously throughout that period, as evenly spaced as possible, aiming for about 100 targets altogether. Each target will be available for prediction for a period of three weeks, although in some cases we request a longer period to allow it to be used to test refinement methods. It is of course important that there not be any kind of public release of the experimental structure (including things like pictures on web pages or abstracts) until after the predictions for that target are closed. As many of you know, it's fairly simple, with just two things to bear in mind. First, because of the timing framework, there needs to be at least a month between the submission date and any release of the structure. Second, we ideally need the experimental co-ordinates by the beginning of August and definitely by the end of August, so that the predictions can be assessed. At that point, they can be kept confidential if necessary, though we would like to provide them to predictors of your structure at the beginning of November at the latest, so that can see how well they have done. Participants would also usually like to be able to show slides and discuss their predictions at the meeting at the beginning of December. So, if you have any thing suitable, we would be most grateful if you would go to the target entry page: http://www.predictioncenter.org/casp10/targets_submission.cgi 1.

[ccp4bb] CASP Roll: Call for novel fold and membrane protein targets to help improve structure modeling methods
Dear colleagues, As many of you know, the CASP community experiments have been running once every two years since 1994, collecting information on soon to be solved structures from the experimental community, and passing on sequence data to the structure modeling community so that blind predictions of structure can be collected and assessed (1). Over that period CASP has seen enormous progress in the quality of modeled structures (2), but many problems remain. The regular CASP experiments collect target information for a three month season every two years, and in that period, thanks especially to the structural genomics community, can acquire over 100 targets, sufficient to evaluate the state of the art for most types of template based modeling. There are some classes of target, specifically proteins with novel folds and membrane proteins, where there are not enough structures solved in three months to provide sufficient information so the methods can be fully evaluated. As a consequence, progress is slowed. To address this problem, with the encouragement of the modeling community, CASP has launched a rolling mechanism, where we accept targets in these categories at any time. Of course for that to work we rely on you, the experimentalists, to provide suitable targets! So we are asking that you tell us about structures in these categories that are about to be solved whenever they come up. For those of you who have not provided targets to CASP before, the procedure is simple – there is a web page for submitting targets, and a very experienced staff to deal with any queries. We don’t need the structure in advance of its release by the PDB, and if we are notified early enough (a minimum of three weeks before release, more is better) there need be no delay in structure release. If you have a suitable target now, we are up and running with 50+ prediction teams already submitting models, and would love to have your targets. Most important, the modeling community is now in continuous need of your assistance, so please get in touch whenever an opportunity arises in the future, and help improve modeling methods.
