A, B	PF09252	Allergen Fel d I-B chain (Feld-I_B)	Allergen Fel d I-B chain	Members of this family of cat allergens adopt a helical structure consisting of eight alpha helices, in a Uteroglobin-like fold. They are one of the most important causes of allergic asthma worldwide [1].	Domain
A, B	PF01099	Uteroglobin family (Uteroglobin)	Uteroglobin family	Uteroglobin is a homodimer of two identical 70 amino acid polypeptides linked by two disulphide bridges. The precise role of uteroglobin has still to be elucidated [1].	Domain
