Protein ID (Genbank)


Protein ID (Genbank)search for term

The Protein ID is an identification number assigned to the amino acid sequence data included within a sequence record. This sequence identifier uses the accession.version format. Each protein ID is made up of three letters followed by five digits, a period, and a version number. For example, in a sequence record M12345, the Protein ID for the sequence translation could be AAA35650.1. If the protein sequence data changes in any way (even by just one amino acid), the version number in the Protein ID will be increased by an increment of one, while the accession number base remains constant. For example, AAA12345.1 would become AAA12345.2. Each amino acid sequence change also results in the assignment of a new GI number to the altered protein translation.
