Ephrin type-A receptor 2 (EphA2) is a tyrosine kinase that initiates both ligand-dependent tumor-suppressive and ligand-independent oncogenic signaling. We used time-resolved, live-cell fluorescence spectroscopy to show the ligand-free EphA2 assembles into multimers driven by two types of intermolecular interactions in ectodomain. The first type entails extended symmetric required for ligand-induced clustering signaling inhibits activity extracellular signal–regulated (ERK) protein B (AKT)...

Although many these treatments produce impressive initial responses, eventual resistance onset is practically unavoidable. One the main approaches for preventing this refractory condition relies on implementation combination This includes dual-specificity reagents that affect both their targets with high level selectivity.

ABSTRACT The EphA2 receptor tyrosine kinase mediates ligand-induced canonical signaling associated with tumor suppression and ligand-independent noncanonical implicated in progression. Using time-resolved fluorescence spectroscopy live cells, we find that unliganded receptors pre-assemble into multimers, which is mediated by two symmetric one asymmetric interfaces the ectodomain. Upon ligand binding, are further assemble large clusters also requires three interfaces. Functionally, disrupting...
EphA2, a member of Eph family receptor tyrosine kinases (RTKs), is overexpressed in multiple types solid human tumors, particularly at the late stages. However, whether and how it drives specific malignant processes remain elusive. We report that EphA2 elevated during prostate cancer (PCa) progression syngeneic murine models. Interestingly, metastatic PCa specimens from two Rapid Autopsy Programs showed selective overexpression metastasis to bone, but not lymph nodes or viscera. Serine 897...
