Specificity
This antibody recognizes high molecular weight antigens in epithelial cells, both on the cell membrane and in the cytoplasm, and reacts with the majority of human epithelial cancers.

UniProt
Immunogen
1C1 was isolated after screening of a non-immunized human Fab phage library. Selection was based on the ability to bind soluble human recombinant EphA2 (residues 183-510). The Fab was subsequently converted to full length human IgG1.
Application Notes
This antibody binds to human Ephrin type-A receptor 2, a receptor tyrosine kinase that binds to membrane-bound ephrin-A ligands residing on adjacent cells, triggering contact-dependent signaling into neighboring cells. Eph2A is involved in pattern formation during development, angiogenesis and osteoblastogenesis. Eph2A has also been found to be expressed in a variety of cancers. This antibody acts as an agonist of Eph2A signaling. The agonist properties of 1C1 is due to ligand mimicry by VDR3. After cell binding, the antibody is able to induce rapid tyrosine phosphorylation, internalization, and degradation of the EphA2 receptor.
