Answer:
E. HER3, but not HER2 binds to its ligand, causing it heterodimerize with HER2. This activates HER2 tyrosine kinase which creates a GRB2 binding site.
Explanation:
The receptor tyrosine-protein kinase, also known as human epidermal growth factor receptor 3 (HER3), is a transmembrane tyrosine kinase receptor that doesn't have a kinase domain. HER3 binds to the HER2 protein (another receptor tyrosine kinase receptor) to form a heterodimeric complex. Conversely to the HER3 protein, HER2 lacks a ligand-binding domain. The HER2/HER3 complex triggers the activation of the HER2 kinase domain which then autophosphorylates and thus generates a binding site for the Growth factor receptor-bound protein 2 (Grb2).
