Inferring Protein Domains Interactions

Question

[User 0063]

Hi all,

I've a set of protein domains sequences. (homolog proteins) I'd like to infer their interactions? Could you give me any suggestion?

Best regards

It's not that clear what you are trying to achieve. For inferring protein-protein interactions, I would use STRING. For inferring protein domain-domain interactions I would use DOMINE although you would need to annotate your sequences with Pfam first.

I've selected domain by InterproScan. I'd like to infer domain-domain interactions

[Pawel Szczesny]

DOMINE also accepts InterPro IDs.

Go through this paper and their software: RCDP , I think its part of DOMINE:

Co-evolutionary analysis of domains in interacting proteins reveals insights into domain-domain interactions mediating protein-protein interactions

InterPare; Paper: A protein domain interaction interface database

InterDom is a database of putative interacting protein domains derived from multiple sources, ranging from domain fusions (Rosetta Stone), protein interactions (DIP and BIND), protein complexes (PDB), to scientific literature (MEDLINE).
