I have got a list of differentially expressed proteins from LC-MS data and have been trying to analyse it for protein-protein interactions (using STRING), functional classification (using PANTHER) among other things.
I found that both STRING and PANTHER couldn't find some IDs (Uniprot accessions). To be precise, out of the list of 39 proteins, STRING couldn't identify 7 and PANTHER a whopping 22 IDs ! Why this difference ?
After doing some recce, I noticed that the unidentified IDs in STRING were unreviewed enteries. One of the IDs was P02751-10 (same as in raw data) which is strange in itself. Is it acceptable to run P02751-10 as P02751 (as the protein name matches with the one in the raw data) ? Is there a way to run these unidentified IDs ?
