Protein Feature Accent

This is a beta version!
Some capabilities are not fully implemented, and there may be bugs or other problems. Please use with care and a sense of humor. This tool requires that Java be installed on your computer.

Purpose:   The Protein Feature Accent tool is a quick way to map protein sequence features (for example a short functional domain or an epitope) from a sequence directly on to an interactive graphic of the corresponding 3-D structure of the protein.

How to use:   The tool needs only to be directed to use a particular protein structure file in PDB format. Uploading a sequence is not required; the sequence associated with the chosen structure will always be displayed. Any sequences you do provide will be analyzed (for entropy, etc.), aligned with the structure sequence, and displayed.
If you prefer, you may upload a PDB file for a structure you wish to use instead of those available here.
Click here for a list of all the structures available.

New features:

• Predicted N-linked glycosylation site highlighting
• User-supplied alignment entropy color scheme
• PDB file upload option

We are in the process of adding additional features to the tool.
