ORF & Protein Translator

Find open reading frames and translate DNA sequences into amino acid sequences for routine coding-region checks.

ORF and Protein Translator is a browser-based tool for finding open reading frames and translating DNA to protein.

Use note: Use likely coding sequences for Codon Optimizer or Primer Designer during expression planning.

Mode

DNA sequence or FASTA

No sequence loaded.

Upload sequence file (optional)

Accepted file types: .txt, .fa, .fasta, .fna, .ffn, .seq, .gb, .gbk, .genbank. Plain-text DNA, FASTA, or GenBank text only.

Circular DNA/plasmids are not handled as circular yet. For regions that cross base 1, paste the relevant region as linear FASTA or raw DNA sequence.
