# Do any publicly available databases detail protein structure and functional domains?

I am interested in finding a database that takes a gene or protein name as input (possibly with the option to specify transcript) and gives information about the protein's functional domains in terms of either specific residue ranges, genomic coordinates, etc. Ideally, the database would include 3D conformational information as well as the functional domains. Does such a database exist? It seems that this information can be inferred for a given protein using various publications and references but I have yet to find a single collection containing these data all in one place.

• You know about PDB I guess? Jul 26 '17 at 15:33
• @Chris_Rands yeah PDB is great, but to me it seems a bit more like you need to know what you're looking for (ex. EGFR T790M with some kind of binding agent present). I'm looking more for almost a literal diagram or table of the gene detailing relevant functional and confirmation information in a more simplified way. Definitely a source I will be using though.

• Pfam might help too. Jul 27 '17 at 2:57

Some of this information (at least some domains, active sites, etc) is available from UniProt.

• This seems like exactly what I was looking for, for some reason I haven't come across this in my searching. Seems very simple and to the point, also a plus that you can reference the db locally. Thanks!

EnsEMBL also has this. Search for your gene of interest, choose your transcript, go to the page of its protein product(s), and select "Domains & Features" from the right-hand menu (using human p53 as an example):

In addition to UniProt and EnsEMBL as suggested above you might like:

• InterPro, functional analysis of proteins by classifying them into families and predicting domains and important sites.
• ECOD, a classification of protein domains by evolutionary relationship.
• Pfam, a collection of protein families.
• CATH, protein structural domains.
• Genome3D, which combines various resources to structurally annotate proteins.
