Anti-FGFR4 Monoclonal Antibody U3-1784

**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor|Pharmacologic Substance

**Definition:** A human monoclonal antibody against human fibroblast growth factor receptor 4 (FGFR4), with potential antineoplastic activity. Upon administration, U3-1784 specifically binds to and blocks FGFR4. This prevents the activation of FGFR4, inhibits FGFR4-mediated signaling and leads to an inhibition of cell proliferation in FGFR4-overexpressing tumor cells. FGFR4, a receptor tyrosine kinase overexpressed by certain tumor cell types, is involved in tumor cell proliferation, differentiation, angiogenesis, and survival.

**Synonyms:** - U3 1784 - U3-1784
