ORF Finder

ORF Finder searches for open reading frames (ORFs) in the DNA sequence you enter. The program returns the range of each ORF, along with its protein translation. Use ORF Finder to search newly sequenced DNA for potential protein encoding segments. ORF Finder supports the entire IUPAC alphabet and several genetic codes.

Paste the raw sequence or one or more FASTA sequences into the text area below. Input limit is 100,000 characters.:

• ORFs can begin with: any codon atg atg, gtg, ctg, ttg
• Search for ORFs in reading frame 1 2 3 1, 2, and 3 on the direct reverse strand.
• Only return ORFs that are at least codons long.
• Use the standard (1) vertebrate mitochondrial (2) yeast mitochondrial (3) mold mitochondrial (4) invertebrate mitochondrial (5) ciliate nuclear (6) echinoderm mitochondrial (9) euplotid nuclear (10) bacterial (11) alternative yeast nuclear (12) ascidian mitochondrial (13) flatworm mitochondrial (14) Blepharisma macronuclear (15) chlorophycean mitochondrial (16) trematode mitochondrial (21) Scenedesmus obliquus mitochondrial (22) Thraustochytrium mitochondrial (23) genetic code.
