The present invention relates to novel muteins derived from human tear lipocalin, which bind to IL 4 receptor alpha. The sequences of the muteins comprise particular combinations of amino acids. In particular a mutated amino acid residue is present at any one or more of the sequence positions 27, 28 30, 31, 33, 53, 57, 61, 64, 66, 80, 83, 104-106 and 108 of the linear polypeptide sequence of the mature human tear lipocalin. A mutated amino acid residue is also present at any 2 or more of the sequence positions 26, 32, 34, 55, 56, 58 and 63 of the linear polypeptide sequence of the mature human tear lipocalin. The invention also provides a corresponding nucleic acid molecule encoding such a mutein and a method for producing such a mutein and its encoding nucleic acid molecule.

The invention also provides a corresponding nucleic acid molecule encoding such a mutein and a method for producing such a mutein and its encoding nucleic acid molecule.

The present invention relates to novel, specific-binding therapeutic and/or diagnostic proteins directed against Hepcidin, which proteins preferably are muteins of a lipocalin protein. The invention also relates to nucleic acid molecules encoding such proteins and to methods for generation and use of such proteins and nucleic acid molecules. Accordingly, the invention also is directed to pharmaceutical and/or diagnostic compositions comprising such a lipocalin proteins, including uses of these proteins.
