TROP-2 Protein, Human, Recombinant (aa 88-274, hFc)

Tumor associated calcium signal transducer 2 (TACSTD2, TROP-2) is a type I cell surface glycoprotein that is highly expressed on human carcinomas. It was originally identified as an antigen present on human gastrointestinal tumors and is the second of two members of this family. Human and mouse TROP-2 share 87% amino acid (aa) similarity. TROP-2 is capable of transducing an intracellular calcium signal and may play a role in tumor growth. It also has adhesive functions. TROP-2 Protein, Human, Recombinant (aa 88-274, hFc) is expressed in HEK293 mammalian cells with C-Fc tag. The predicted molecular weight is 60-80 KDa and the accession number is P09758.
