Abstract:

To study gene characteristics of shrimp allergen and discuss the mechanism of food allergy, part of Chinese shrimp (Penneropenaeus chinensis) allergen gene was cloned, and its sequence, effective codes, base composition, codon preference as well as amino acid composition of allergen protein were determined. The results showed that the length of shrimp allergen gene is 1034 bp, the allergen protein is composed by 641 amino acids and the codon preference is high. According to the homology comparison between gene and amino acid sequences, the allergen protein of Chinese shrimp is highly similar to that of other sea crustaceans. This might be one of the important reasons to lead to the occur of activity cross reaction among allergen proteins in various seafoods.
