Dear Colleagues, I have a question for all of you bioinformatics oriented structural biologists: How do I predict the sites of protein-protein interactions between two receptors that have been proven to interact biochemically but lack specific details regarding proximity. This is not a straightforward question for me, and I believe it is somewhat complicated. The complicated scenario involves a multitude of different subunits and isoforms. Also, there is not structural data to support all components involved, and thus I presume I should use the sequence based software. I am aware that there are different types of prediction software, either sequence or structure based predictions using different algorithms:http://rosettadesigngroup.com/blog/58/10-protein-protein-interface-prediction-servers/Receptor 1:-Has 5 predicted subunits (Alpha)2-(Beta)2-(Gamma)11. Alpha (6 isoforms)2. Beta (3 Isoforms)3. Gamma (3 Isoforms)Receptor 2:-Is believed to be composed of (Alpha)3-(Beta)21. Alpha (4 isoforms)2. Beta(1 isoform)Any advice or recommendation will be well appreciated! Sincerely, lorenzo
