NCIt definition : A monoclonal antibody directed against the melanosomal membrane protein gp75 (or Tyrosinase-Related
Protein 1 (TRP1)) with potential immunostimulatory and antineoplastic activities.
Anti-gp75 monoclonal antibody IMC-20D7S targets and binds to gp75. This may lead to
the induction of cytotoxic T cell immune and antibody-mediated immune responses against
melanoma cells expressing gp75. gp75, a pigmentation-associated antigen, is expressed
in melanosomes of human melanocytes and melanomas.;
