Novel proteins, gene encoding the same and method of utilization thereof

摘要

The present invention provides, as a gene encoding an antigen recognized by G-CSF-inducing antibodies, a gene encoding: (a) a protein having the amino acid sequence listed as SEQ ID NO:2 of the Sequence Listing; (b) a protein having the amino acid sequence listed as SEQ ID NO:2 of the Sequence Listing with one or more amino acid deletions, substitutions, additions or insertions and also binding to an antibody or its fragment that is active to induce granulocyte colony-stimulating factor; or (c) a protein having at least 50% homology with the amino acid sequence listed as SEQ ID NO:2 and also binding to an antibody or its fragment that is active to induce granulocyte colony-stimulating factor.
