Attenuation of Eph Receptor Kinase Activation in Cancer Cells by Coexpressed Ephrin Ligands
The Eph receptor tyrosine kinases mediate juxtacrine signals by interacting "in trans" with ligands anchored to the surface of neighboring cells via a GPI-anchor (ephrin-As) or a transmembrane segment (ephrin-Bs), which leads to receptor clustering and increased kinase activity. Additionally, soluble forms of the ephrin-A ligands released from the cell surface by matrix metalloproteases can als...
متن کاملDistinctive Structure of the EphA3/Ephrin-A5 Complex Reveals a Dual Mode of Eph Receptor Interaction for Ephrin-A5
The Eph receptor tyrosine kinase/ephrin ligand system regulates a wide spectrum of physiological processes, while its dysregulation has been implicated in cancer progression. The human EphA3 receptor is widely upregulated in the tumor microenvironment and is highly expressed in some types of cancer cells. Furthermore, EphA3 is among the most highly mutated genes in lung cancer and it is also fr...
متن کاملUnliganded EphA3 dimerization promoted by the SAM domain.
The erythropoietin-producing hepatocellular carcinoma A3 (EphA3) receptor tyrosine kinase (RTK) regulates morphogenesis during development and is overexpressed and mutated in a variety of cancers. EphA3 activation is believed to follow a 'seeding mechanism' model, in which ligand binding to the monomeric receptor acts as a trigger for signal-productive receptor clustering. We study EphA3 latera...
متن کاملEph receptor signaling and ephrins.
The Eph receptors are the largest of the RTK families. Like other RTKs, they transduce signals from the cell exterior to the interior through ligand-induced activation of their kinase domain. However, the Eph receptors also have distinctive features. Instead of binding soluble ligands, they generally mediate contact-dependent cell-cell communication by interacting with surface-associated ligand...
متن کاملAdenosine A3 Receptor and Cardioprotection
Ischemic injury to the myocardium is a leading cause of morbidity and mortality around the globe.1 It is worth remembering, however, that this insult to the heart emerged only in the last few centuries, an instant in time from an evolutionary perspective. Thus, any cardioprotective responses to ischemic injury undoubtedly evolved for an entirely different purpose. Beyond pure academic interest,...
