Protein Structure and Function Analysis (SS 2013)

This is the main information exchange for the practical on Protein Structure and Function Analysis in 2013. The organisers (Edda, Andrea, Lothar) publish short introductions into the tasks, which are roughly organised by days of the practical. Students add their talks and use this site to document their methods and results. - You can log in to edit with the credentials for the Rostlab/Kramer student computer cluster.

Tasks

1. Collect information on the individual disease
2. Run sequence searches on the disease gene product and produce alignments
3. Prediction of different features from protein sequence
4. Structural alignment, evaluation of alignments using structures
5. Homology based structure prediction
6. Protein structure prediction from evolutionary sequence variation
7. Researching SNPs
8. Sequence-based mutation analysis

Diseases

In this practical, we analyse the mutations causing a number of genetic diseases (see disease list). For each disease, one page summarises the information on the genetic disease. From there, we link to pages detailing the analysis results for the individual mutated sequences.

Example/Template

1. Canavan Disease
2. Gaucher Disease
3. Hemochromatosis
4. Maple Syrup Urine Disease
5. Phenylketonuria

Resources

Here, we collect links to resources used throughout the practical. This list is maintained by the organisers and the students. Please also include a short description of the resource if you add something. (Also, feel free to add to the existing descriptions.) The resources can be related to

• Literature
• Wiki editing
• Software
• Databases
• Language
• Discussion

Deadlines

• August 31: Finalize wiki
• September 30: Hand in report

What to put on the Wiki

The wiki entries referring to the tasks have several purposes:

• Use it as a lab journal to document what you did (make your results reproducible): e.g. collect what your command line looked like, which files your results are stored in, etc.
• Document your results: Describe what you observed.
• Discuss the outcome: Try to make sense of what you observed. Would you have expected that outcome? Why / why not?

We recommend to separate the "lab journal" part from the Results and Discussion part.

• Deadline: August 31

Report

Write a report of your findings during the practical. Guidelines:

• max. 5 pages
• Bioinformatics style. Templates of the journal can be found here for LaTeX and Word.
• Scientific report, i.e. should not contain ALL your results, but (based on your results) present an interesting story.
• Remeber: spellcheck, reference your sources, reference your figures in the text, font size in figures should be large enough to be readable, paragraphs min. 3 sentences, but not too long, sentences not too long.
