Abstract: Disclosed herein are methods and compositions engineered to modulate ephrin type-A receptor 2 (EphA2), including novel compositions comprising one or more dimeric peptide units that binds to a EphA2, wherein the dimeric peptide comprises two or more homologous sequences or fragments thereof, wherein the two or more homologous sequences or fragments thereof, individually, comprise one or more binding sites for the EphA2 with unexpectedly high specificity and binding affinity. The compositions described herein can be attenuated to treat subjects suffering from diseases and/or conditions.

Abstract: Novel agents are described that bind to Eph receptors. Methods of using these agents to modulate the activity of Eph receptors, stimulate apoptosis, and deliver therapeutic agents are also described. Methods of screening for agents capable of selectively binding to Eph receptors are also described.

Abstract: The application is related to the identification of peptides that selectively bind to Eph receptors of the B class. Also disclosed are uses of such peptides in the treatment of a variety of diseases. Additionally, imaging tumors in patients is described by administrating labeled peptides to patients and then obtaining an image of the labeled peptides.

Abstract: The invention is directed to substantially purified Eph-related protein tyrosine kinases, or functional fragments thereof, having about 23 to 66 percent amino acid sequence identity in their carboxyl terminal variable regions compared to known members of the Eph subclass of tyrosine kinases. Nucleic acids encoding such Eph-related protein tyrosine kinases, vectors and host cells are also provided. The invention is also directed to a method of diagnosing cancer and determining cancer prognosis. The method includes removing a tissue or cell sample from a subject suspected of having cancer and determining the level of Eph-related protein tyrosine kinase in the sample, wherein a change in the level or activity of a Eph-related protein tyrosine kinase compared to a normal sample indicates the presence of a cancer or indicates the level of malignancy of a cancer.
