This family consists of proteins from plants, animals and fungi, including dust mite allergen Der P 2 (Swiss:P49278). It has been implicate in lipid recognition, particularly in the recognition of pathogen related products. A mutation in Npc2 (Swiss:Q15668) causes a rare form of Niemann-Pick type C2 disease. This domain has a similar topology to immunoglobulin domains.	Domain
