Anti-Trop-2 Antibody

The protein known as Trop-2, or also known as cell surface glycoprotein Trop-2, Membrane component chromosome 1 surface marker 1 or Pancreatic carcinoma marker protein GA733-1 and encoded by the gene TACSTD2/GA733-1/M1S1/TROP2, is a protein that may function as a growth factor receptor and is expressed primarily in the placenta, lung and epithelial tissues but also found expressed in pancreatic cancer cell lines. Interestingly, this protein′s gene is intronless, a rare event in eukaryotic genes, and was first identified as a carcinoma antigen by the monoclonal GA733. It is a plasma membrane bound protein that transduces an intracellular calcium signal and appears to act as a receptor for as yet unidentified growth factors. Interestingly too, mutations in this gene are associated with a rare cause of blindness with amyloid protein bodies (insoluble fibrous protein aggregates but not always of amyloid protein) beneath the cornea. Trop-2 has also recently been shown to be important in regulating fibroblast motility and lung cell proliferation and does so by regulating the ERK kinase pathway as well as several critical components of the cell migration apparatus.
