You can use the bioconductor package "STRINGdb", assuming you're a little comfortable using R programming language. Basically, you can obtain your PPI network with 3 commands:

string_db=STRINGdb$new(version="10",species=9606,score_threshold=400,input_directory="YOUR_PATH")

myDF=string_db$map(myDF,"GENE_NAME",removeUnmappedRows=TRUE)

string_db$plot_network(myDF$STRING_id,n=200)

The first line generates a STRINGdb object containing some parameters for further computation (e.g. specie, PPI score threshold, etc.).

The second line takes a data frame (myDF) in input and converts column "GENE_NAME" containing gene symbols into a new column called "STRING_id". Note that "removeUnmappedRows=TRUE" will remove unknown gene symbols.

The third line plots your network using the new column with STRINGdb entries.

Cheers.

I suggest to convert your list to uniprot id:

• cut and paste you list here http://www.uniprot.org/uploadlists/
• select Entrez Gene to uniprotKB
• download the list of targets
• upload the list of targets here http://www.ebi.ac.uk/intact/

what kind of id you have for your genes? you can directly upload your ids here http://www.ebi.ac.uk/intact/ and retrieve the interactions. Alternatively, you could use http://www.uniprot.org/uploadlists/ to retrieve the mapping genes-proteins

I have Gene_Entrez and Gene_Symbols. Could you explain this a little bit how can I know my genes in this case if I used http://www.ebi.ac.uk/intact/ or http://www.uniprot.org/uploadlists/
