Chapter 14, Problem 17P
Interpretation Introduction

Interpretation:

Mechanism for NGF signaling pathways and the secondary messenger produced during this should be determined.

Concept introduction:

Nerve growth factor is a neuropeptide that is responsible for the growth, proliferation, maintenance, and survival of the certain target neurons. NGF binds to two kinds of receptors, tropomyosin receptor kinase A, and low-affinity NGF receptor. The mutation in any of these receptors can lead to neurodegenerative disorders.

Inducers and Inhibitors of AEP. Short peptides such as legumain stabilization and activity modulation (LSAM) domain and αvβ3 integrin could enhance the activity of AEP. LSAM domain known as the prodomain of AEP blocks substrate binding before activation. This prodomain has a helical structure and two independent peptides. One is an activation peptide (AP, K287 to N323), and the other is a LSAM domain. LSAM domain remains even after AP is cleaved and released from protease at neutral pH via electrostatic interaction. AEP without LSAM domain has a lower melting temperature than AEP with LSAM domain [77, 117]. Another short peptide, αvβ3 integrin, can directly interact with AEP, and after forming a complex, the optimal pH for AEP activity is increased from 5.5 to 6.0. It indicates that αvβ3 binding could induce conformational stabilization of AEP accompanied by deprotonated C189. αvβ3 does not directly interact with the AEP active site; however, AEP docks to the αvβ3 RGD-binding site…
Cell signaling. The ER doctors gave a patient an injection of epinephrine to increase his heart rate and blood pressure. The heart rate and blood pressure went up but not enough. The second dose of the same drug seemed not to have an effect. What do you think may be a possible explanation for this result?
Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn).  In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds.  The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true: Question 21 options: profilin in a molecular motor profilin is a promoter of actin polymerization profilin replaced G-actin in an F-actin strand and breaks the filament profilin is an inhibitor of actin polymerization profilin binds to G-actin, preventing it from polymerizing
