Patinopecten yessoensis ferritin gene and application thereof

The invention relates to a patinopecten yessoensis ferritin gene and the application of the gene. The ferritin gene is separated from patinopecten yessoensis and has the protein sequence as shown in SEQ ID NO. 1 and the cDNA sequence as shown in SEQ ID NO. 2. According to the invention, the patinopecten yessoensis ferritin gene is cloned, and iron oxidation and bacteriostatic activity analysis are carried out on the in vitro recombined expression product. The research proves that patinopecten yessoensis ferritin gene not only has the functions of chelated iron, but also has bacteriostatic activity, thus the patinopecten yessoensis ferritin gene can inhibit the growth of important pathogenic bacteria of shellfishes. Thus, the patinopecten yessoensis ferritin gene has good application potential in disease control.
