Sequence submission: paste the sequence(s) and/or upload a local file
Enter a regular expression: RR.[FGAVML][LITMVF]
Submit a file in FASTA format directly from your local disk:
We recommend that only the N-terminal part of each protein sequence is submitted. Enter 0 (zero) to disable truncation.
Restrictions: At most 4,000 sequences and 2,000,000 amino acids per submission; each sequence not more than 5,000 amino acids.
Confidentiality: The sequences are kept confidential and will be deleted after processing.
