You can use 'string' its a very good program available online for free

Try Swissprot, there are many tools...

Have you tried Modeller, I-Tasser, Swiss-Model? What about NCBI RefSeq?

Dear all,

Thank you so much nice references.

Some more PPI resources are -

1. DIP: Database of Interacting proteins available at

http://dip.doe-mbi.ucla.edu/dip/Main.cgi

2. Other databases: BIND, Binding DB etc.

3. Tool for visualization of interactions: Cytoscape

4. Antigen-antibody interactions are a special class of protein-protein interactions.

If you are interested in this category, pl visit, Antigen-Antibody interaction database

(AgAbDb) at http://117.239.43.117:8080/agabdb2/home.jsp

I will go for;

Database: STRING

Visualization tool: Cytoscape
