I used STRING db in order to find all the interactions of the precursor protein APP. What I specifically need is a confirmation (supported by some article and experiments in it). But significant amount of interactors have only "Database" confirmation (mostly relaying on Reactome and KEGG data). Searching in these db's gives me neither article nor even the presence of these proteins in one pathway (what's weird). How can I obtain the data?
P.S. If it's possible to use API for getting all the articles -- that'd be great.
Thanks in advance!
