What type of signaling molecule is molecule a

Reference no: EM133492454

You are working in a lab studying a receptor kinase that is involved in a stress response signaling pathway. Signaling molecule A binds to the receptor kinase causing dimerization and protein B is activated via phosphorylation by an activated Ras signaling protein. Protein B then phosphorylates protein C which translocates to the nucleus and activates (also by phosphorylation) protein D. Protein D is located in the nucleus and interacts with RNA polymerase to express genes involved in stress response.

Question A. What type (hydrophobic or hydrophilic) of signaling molecule is molecule A? How do you know? Explain your answer.

Question B. What type(s) of amino acids e.g. nonpolar or polar will interact with signaling molecule A? Explain your answer.

Question C. What type of protein is protein B? Explain your answer and describe the function of protein B.

Question D. Do you think there would be a change in the expression of stress response genes if there was a missense mutation in protein D? Explain your answer and the function of protein D.
