Provided is a human C-type lectin, binding molecules that specifically bind to the human C-type lectin, nucleic acid molecules encoding the binding molecules or the human C-type lectin, compositions comprising the binding molecules or the human C-type lectin and methods of identifying or producing the binding molecules. The human C-type lectin is specifically expressed on myeloid cells and binding molecules capable of specifically binding to the human C-type lectin can be used in the diagnosis, prevention and/or treatment of neoplastic disorders and diseases.
