Hello guys

I have downloaded biogrid​ ppi data and integrate same in a MySQL database. I have also downloaded UniProt and others will be downloaded and integrated in a MySQL database. My question is that how do I map all this data with all the databases as mentioned in the post title. By which ID can I map records?

Besides, can I download the GO data (biological process, molecular function & cellular component) from UniProt directly or I have to download it from Gene Ontology?

To be more precise, if I select an ID from BioGRID table, this should provide me all corresponding info in UniProt, PDB, InterPro, NCBI Gene and NCBI Taxonomy. How can I achieve this?

Thanks & Regards
