Patatin
Appearance
Patatin is a family of glycoproteins found in potatoes (Solanum tuberosum). They have a molecular weight ranging from 40-45 kDa, but are commonly found as a 80kDa dimer.[1] The main function of patatin is as a storage protein but it also has lipase activity and can cleave fatty acids from membrane lipids.[2][3] The patatin protein makes up about 40% of the soluble protein in potato tubers.[4] Members of this protein family have also been found in animals.
Allergy
Patatin is identified as a major cause of potato allergy.[5]
