      Replacement Information
      Description
      OverviewRecombinant, human ErbB2 fused at the N-terminus to a GST-thrombin cleavage site sequence and expressed in S. frugiperda insect cells using a baculovirus expression system. ErbB2 is a component of a neuregulin-receptor complex that regulates neuromuscular synapse formation. It plays an important role in muscle spindle development. Overexpression of ErbB2 is reported in ~30% of all breast cancer cases. Amino acid sequence human ERB2 679-1255.
