Target Background

Receptor tyrosine kinase which binds promiscuously membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Binds with a low affinity EFNA3 and EFNA4 and with a high affinity to EFNA1 which most probably constitutes its cognate/functional ligand. Upon activation by EFNA1 induces cell attachment to the extracellular matrix inhibiting cell spreading and motility through regulation of ILK and downstream RHOA and RAC. Plays also a role in angiogenesis and regulates cell proliferation. May play a role in apoptosis.

  11. High Eph A1 expression is associated with choriocarcinoma invasion. PMID: 23429488
  12. Results show that EphA1 appears to be a differentiation marker for esophageal squamous cells, and its increased expression is positively associated with lymph node metastasis and advanced disease stage. PMID: 23030051
  13. EphrinA1 is released in three forms from cancer cells by matrix metalloproteases PMID: 22688511
  14. The present study reveals a novel function for EphA1 and EphB2 in the induction of autophagy, suggesting a tumor suppressor role for these proteins in colorectal cancer. PMID: 21503576

  16. Common variants at MS4A4/MS4A6E, CD2AP, CD33 and EPHA1 are associated with late-onset Alzheimer's disease. PMID: 21460841
  17. The EphA1 expression level is a potential prognostic marker in gastric carcinoma, and may provide a novel target of therapy for gastric carcinoma. PMID: 21042754
  18. Eph-A1 staining intensity was significantly associated with tumor size and tumor histopathological stage in pancreatic ductal adenocarcinoma PMID: 19949912
  19. Suppression of EphA1 expression in Huh-7 cells reduced their outgrowth when inoculated in the subcutaneous space in the flank of nude mice, presumably through angiogenesis inhibition since microvessel density was found to be inhibited. PMID: 20043122
  20. EphA1 seems to be a marker of the differentiated normal epidermis and its downregulation in nonmelanoma skin cancer may contribute to carcinogenesis of these very frequent human tumors. PMID: 16862074
  21. I 12 acquired a higher affinity toward EphA2 with K(d) 18 nm and inhibited vascular endothelial growth factor-dependent angiogenic invasion in a Matrigel plug assay PMID: 18308734
  22. Results suggest that EphA1-receptor transmembrane domains contribute to the dimerization-mediated receptor activation. PMID: 18590698
  23. analysis of the spatial structure and pH-dependent conformational diversity of dimeric transmembrane domain of the receptor tyrosine kinase EphA1 PMID: 18728013
