Why is homeostasis important for cells? Why do enzymes have different optimum pH and temperatures? How do most cells regulate the activity of enzymes? Explain how restriction enzymes work. How do protein kinases affect enzymes? Why does an enzyme function as a catalyst in a reaction?
Prominent examples of such beneficial "toxins" are trace metals such as selenium, chromium, and zinc. Fundamental inter- and intracellular signals also exhibit hormetic dose responses, including hormones, neurotransmitters, growth factors, calcium, and protein kinases. Moreover, everyday health-promoting...
Why is the double helix important for DNA replication? Why are there more mutations in introns vs. exons? What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication? Why does a single cell require hundreds of protein kinases?
While the role of kinases in the DDR has been well documented, the complex roles of protein dephosphorylation have only recently begun to be investigated. Therefore, it is important to focus on the role of phosphatases and to determine how their activity is regulated upon DNA damage. In this ...

As PTP1B and the zinc trans- porter ZIP7 are both localized on the ER membrane, zinc influx through ZIP7 may play an important role in the regu- lation of PTP1B activity [118]. Zinc and receptor tyrosine kinases Zinc is found to induce phosphorylation of a variety of receptor ...
Chapter 2: Understanding Structure—Function Relationships in the Aequorea victoria Green Fluorescent Protein Both GFP and aequorin can dimerize under appropriate conditions, and it is the dimerized forms that are believed to interact. The molecular details of the... AB Cubitt,LA Woollenweber,R Heim...
Why are triglycerides cleaved and then reformed in intestinal cells? Why do lipid ligands not require receptor proteins? Why are some steps in glycolysis irreversible? Why are vesicles important in maintaining homeostasis? How do protein kinases affect enzymes?
