Proteopedia Eran Hodis, Jaime Prilusky, Eric Martz, Joel Sussman A Tool to Make 3D Structural Data More Comprehensible

Markus Fisher, Katie Rosa, Barry Honig Thank you

It’s hard to believe, but… 3D structures are often times hard to understand -- even for a structural biologist!

Structural biology everywhere 13 Nobel prizes since 1st protein structure solved Covers on Nature, Science, Cell, …

Growth in PDB 53,521 structures but… Oct 7, 2008

But, structural biology still suffers from a communication problem Often communicating 3D in 2D And not that accessible to non-structural biologists that don’t have experience with molecular visualization programs Structural Biology, needs to make a special effort to develop tools for communication and accessibility, specifically better tools to integrate 3D structure with functional information

Proteopedia Built on Open Source tools: –MediaWiki –Jmol Content is free under GNU FDL license (same as Wikipedia). Proteopedia just the vehicle for creation & dissemination Content - can be added by anyone, easily via user friendly authoring tools to link text to 3D structures.

A wiki for the scientific community Names of contributors are listed on each page to give credit & add responsibility

A wiki for the scientific community Each User can have a special area that only she/he can edit - useful for: Tutorials Lectures Supplementary information for journal articles

Proteopedia is already in use & evolving with feedback (over 200 registered users)

How are people using it? As a 3D encyclopedia and…

What to expect as a Viewing User? Explore, but don’t expect to find a well-developed page on your favorite protein Use the PDB entry pages to get Abstract + 3D structure on the same page

Proteopedia allows you to be creative Even though the tools are here, and the technical barriers lowered dramatically via Proteopedia’s relative ease of use … It still takes some thought to make a good page!
