Where can I find human protein data base for local blastx? I have already blasted my transcriptome against the nr database. My adviser wants me to blast it against the human protein database and find out the genes named same way in both nr database and human database. I checked the ncbi ftp but couldn't find anything.
I suggest you have a look at these documents which explain how to retrieve and download all human proteins from the UniProt Knowledgebase:
One of the download formats is fasta (I recommend "fasta (canonical and isoforms)"), from which you should be able to generate a BLAST database.
