Protein and RNA alignment and analysis with Jalview 2.8.2 and JABA 2.1
Download as PPTX, PDF•2 likes•5,205 views
This document provides an overview of the Jalview 2.8.2 and JABA 2.1 software for protein and RNA alignment analysis. Key features include an interactive Java alignment viewer and editor, integrated structure viewers, and predictive annotation of secondary structure. Upcoming updates focus on consensus-based RNA structure prediction and utilizing 3D structural data for protein and RNA annotation directly in the alignment. The software continues to be developed and maintained by the Barton Group at the University of Dundee.

- 16. THE JALVIEW 2.8 SERIES
- 17. IT’S (NEARLY) ALL ABOUT STRUCTURE!
- 18. Jalview 2.8 and RNA 2nd-ary Structure Structure Consensus Logo: Shows base pair distribution at each paired position in a given RNA secondary structure. Linked VARNA RNA Secondary Structure viewer and editor. RALEE style colouring highlights distinct stems and helices
- 19. 2.8.1 - Interactive Alignment based RNA 2nd-ary Structure Prediction
- 20. 2.8.1 - Interactive Alignment based RNA 2nd-ary Structure Prediction • Shares framework with AACon consensus client • Predictions update when alignment changes • settings & results saved in Jalview project Implemented by our 2013 Summer student
- 21. When ‘partition function’ enabled, the contact probabilities are displayed
- 22. Tooltips provide additional RNAAliFold information
- 23. Protein Secondary Structure Prediction • Neural network trained on amino acid profiles – Predicts Helix, shEet, or Coil based on sliding window • Also predicts coiled coils and surface accessibilities • Server can take – Single Sequence • Service computes profile with PSI-Blast – Alignment • Service uses MSA to calculate profile for prediction SLOW FAST! Interactive JPred3 MSA annotation now in 2.8.2 alpha
- 24. 2.8.2 alpha - New look Jpred results Burial now encoded as quantities Burial and other predictions can be used to colour/filter alignment data
- 25. Secondary structure from 3D data • Jmol includes a Java port of DSSP – Courtesy of the Vriend Lab • Jalview 2.8.2 now employs Jmol to parse PDB data – Display residue level structure data on sequences http://jmol.sourceforge.net/
- 26. RNAView, pyRNA • Fabrice Jossinet’s pyRNA server includes RNAView* – Identify and characterise base pair interactions in 3D structure • Used by Jalview to obtain secondary structure for RNA 3D data * RNAView will shortly be replaced by DSSR (Xiang-Jun Lu) http://x3dna.org/index.php
- 27. • Functionality still to be implemented – Colour sequences by protein as well as RNA secondary structure – Show/hide per-sequence structure rows – Representative/consensus 2nd-ary structure for a sequence
- 28. Things I haven’t talked about … Currently available in v 2.8.1 • Internationalisation (Spanish, so far) • View flanking regions (Proteomics) • More score models for PCA/Trees • View ‘representative structures’ • Select columns by feature..
- 29. Select column by feature
- 30. Roadmap for Jalview 2.8.2 E.T.A September 2014 • Interactive consensus secondary structure annotation for protein alignments – JABA Jpred MSA prediction mode • Structure based RNA + Protein annotation – Jmol DSSP and XRNA 2.5D • Prototype Chimera/Jalview interconnect • Feature/Annotation based trees/PCA – Cluster by • Secondary structure • Displayed sequence annotation
