  • Target

    • FunctionReceptor for members of the ephrin-A family. Binds to ephrin-A1, -A3, -A4 and -A5. Plays an important role in angiogenesis and tumor neovascularization. The recruitement of VAV2, VAV3 and PI3-kinase p85 subunit by phosphorylated EPHA2 is critical for EFNA1-induced RAC1 GTPase activation and vascular endothelial cell migration and assembly (By similarity). Induces apoptosis in a p53/TP53-independent, caspase-8-dependent manner.
    • Tissue specificityExpressed in brain and glioma tissue and glioma cell lines (at protein level). Expressed most highly in tissues that contain a high proportion of epithelial cells, e.g., skin, intestine, lung, and ovary.
    • Involvement in diseaseGenetic variations in EPHA2 are the cause of susceptibility to cataract cortical age-related type 2 (ARCC2) [MIM:613020]. A developmental punctate opacity common in the cortex and present in most lenses. The cataract is white or cerulean, increases in number with age, but rarely affects vision.
      Defects in EPHA2 are the cause of cataract posterior polar type 1 (CTPP1) [MIM:116600]. A subcapsular opacity, usually disk-shaped, located at the back of the lens. It can have a marked effect on visual acuity.
    • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily.
      Contains 2 fibronectin type-III domains.
      Contains 1 protein kinase domain.
      Contains 1 SAM (sterile alpha motif) domain.
    • Post-translational
      modifications
      Activated by EFNA1 via tyrosine phosphorylation. Phosphorylated residues Tyr-588 and Tyr-594 are required for binding VAV2 and VAV3 while phosphorylated residues Tyr-735 and Tyr-930 are required for binding PI3-kinase p85 subunit. These phosphorylated residues are critical for recruitment of VAV2 and VAV3 and PI3-kinase p85 subunit which transduce downstream signaling to activate RAC1 GTPase and endothelial cell migration. They also play a critical role in transducing EPHA2 signaling in vascular endothelial cells during tumor angiogenesis.

    • FACS analysis of BOSC23 cells using ab59551 at 1.2 µg/ 106 cells. BOSC23 cells were transiently trans-fected with an expression vector encoding either EphA2(red curve) or an irrelevant protein (control transfectant).Binding of ab59551 was detected with a PE-conjugatedsecondary antibody.
    • Spectral Confocal Microscopy of CHO cells using ab59551 at 1µg/106 cells. CHO cells were transiently transfected with an expression vector encoding EphA2. Binding of ab59551 was visualized with a FITC-conjugated secondary antibody (green). Actin filaments are labeled with Alexa Fluor-555 Phalloidin (red). Cell nuclei are stained with DAPI (blue).
