Food Allergy: Polcalcin Proteins

What are they?

Polcalcin are calcium binding proteins found in a relatively large group of plants. These proteins are involved in signaling processes (chemical signals between plants cells) and pollen tube growth.

They are found in tree, grass and weed pollens. They are very cross-reactive.

Polcalcin proteins have low sensitisation rates compared to other allergenic proteins and are therefore considered to be minor pollen panallergens. Other pollen panallergens are Bet v 1 allergens, profilin proteins and lipid transfer proteins.
