Surface proteins

[Pedramto89]

Hi.

I did the protein-protein interactions (PPIs) analysis and I have the csv file now after I melted the results. Now, I am wondering how can I filter the PPIs based on their location, limited to surface proteins? Thanks!

This is the summary of my data:

Hi Pedramto89,

The location information (see cols: peripheral, transmembrane, secreted, receptor and integrin in https://github.com/ventolab/cellphonedb-data/blob/master/data/protein_input.csv) is a characteristic of the protein and we could assume that this is where the interaction would happen, but we do not have a validated evidence). The above caveat not withstanding, in short you can filter the interactions if they involve at least one protein that is a receptor, transmembrane, or integrin, etc

Hope that helps,

Robert.
