The present invention provides a bispecific antibody construct comprising a first human binding domain which binds to human CDH19 on the surface of a target cell and a second binding domain which binds a human CD3 on the surface of a T cell. Moreover, the invention provides a polynucleotide encoding the antibody construct, a vector comprising the polynucleotide and a host cell transformed or transfected with the polynucleotide or vector. Furthermore, the invention provides a process for the production of the antibody construct of the invention, a medical use of the antibody construct in the treatment of melanoma, and a kit comprising the antibody construct.
