What are they?
Many plant and animal tissues contain profilin proteins. They are small proteins involved in the assembly of actin filaments. Actin filaments in plants determine the shape and movement of the cell’s surface.
Profilin proteins are considered to be minor panallergens. They are less commonly associated with allergy than lipid transfer proteins and seed storage proteins, but have become more studied in recent years due to the possibility of cross reactivity.
These proteins vary from species to species in how the allergenicity is changed due to heat, but most studies show many are heat resistant and will still elicit an allergic reaction after cooking or processing.
