UniProtKB release 2017_10 plus isoforms (93,832,727 sequences)

Retrieve protein sequences that would exactly match to your query peptide

1. Select sequence data set:
    a) All UniProtKB plus isoform sequences
    b) Restricted by organism:
        Enter an organism from UniProt complete proteomes list

        Select organisms from UniProt reference proteomes list
          [A] [B] [C] [DE] [FG] [H] [IJKL] [M] [NO] [PQ] [R] [S] [T] [UVWXYZ]
2. Insert a peptide using single letter amino acid code (3 or more) below:

3. Options:
   a)Limited to UniRef100 representative sequences within the UniProtKB
    Yes    No

   b)Treat Leucine (L) and Isoleucine (I) equivalent
    Yes    No

    Delays may be experienced due to heavy loads on our server or network traffic.
