Routes of exposure:
Include only IUIS approved allergens.

Biochemical properties

Hsp70 proteins are ubiquitous chaperones that catalyze protein folding driven by hydrolysis of ATP [1].

Allergens from this family

Allergens belonging to the Hsp70 family are found in a heterogeneous range of sources. Several fungal allergens belong to this family such as Mala s 10 from Malassezia sympodialis [2] and Alt a 3 from Alternaria alternata. In addition, the hazel pollen allergen Cor a 10 [3] and Der f 28 from the mite Dermatophagoides farinae [4] belong to this family.
