  • Target

    • Relevance
      Ephrin B proteins are thought to play key roles in cellular functions as diverse as neuronal migration and blood vessel development. Ephrin B molecules expressed at the membrane surface bind to the Ephrin B family receptors on target cells during cell to cell contact. This interaction leads to cell signaling in the target cell but also generates a reverse signal in the cell expressing Ephrin B on its surface. This reverse signaling event is thought to be critical for vessel maturation and neuronal development. Importantly, tyrosine phosphorylation of Ephrin B is thought to be a critical component of this reverse signaling event. Recent work demonstrated that Tyr331 of Ephrin B was phosphorylated in HEK293 cells after stimulation by the soluble Ephrin B2 receptor tyrosine kinase.

      Lane 1 : Rat testes lysate treated with this Ephrin B antibody phosphorylated at Tyr317 (control).
      Lane 2 : Rat testes lysate incubated in lambda phosphatase (1200 unit for 30 min) before being exposed to this Ephrin B antibody phosphorylated at Tyr317.

      Lysates/proteins at 50 µg per lane.

      Predicted band size : 37 kDa
      Observed band size : 46 kDa (why is the actual band size different from the predicted?)
      Additional bands at : 100 kDa. We are unsure as to the identity of these extra bands.
