Blast BRAKER output

Question

[Tom Brady]

I ran BRAKER on my genome assembly, and got a .gtf file with all the genes, and a .aa file with all the protein sequences. I wanted to BLAST the proteins to add a gene_name field to the gtf with the actual gene symbols, but I'm not sure what uniprot database would be best to blast it against?

[GenoMax]

Is there a proteome available for a close relative? Then it may be an option depending on how complete it is in UniProt. If you want to broaden the scope then one of the UniRef databases: https://www.uniprot.org/help/uniref
