Your Research Project Involves the Characterization of a Particular Signal

question 43

Multiple Choice

Your research project involves the characterization of a particular signal transduction pathway.Specifically,you have been studying a receptor tyrosine kinase and protein X,which initiates downstream events.You are certain that protein X is part of the signal transduction pathway,but have been unable to identify a direct protein-protein interaction between the receptor tyrosine kinase and the protein X.What should you do next in your attempt to identify a link between the receptor tyrosine kinase and protein X?

• A)Try to identify a coactivator protein.
• B)Try to identify proteins that act downstream of protein X.
• C)Try to identify an adapter protein that can interact with both the receptor and protein X.
• D)Confirm the interaction between the receptor tyrosine kinase and its ligand.
