In expressing therapeutic proteins (check all that apply):O Bacteria could be used if you want the protein's disulfide bonds formed before secretion from the bacterial cell.The N-terminal signal sequence and the C chain of insulin must be cleaved off in the rough ER before it's active.O Proteolytic protein maturation can be performed by mammalian cells.□ One of the required modifications to preproinsulin, before it's mature, is glycosylation.Both preproinsulin and proinsulin are inactive proteins.

Therapeutic proteins are genetically engineered proteins of mammalian origin. These proteins are…

. CTP synthetase catalyzes the glutamine-dependent conversion of UTP to CTP. The enzyme is allosterically inhibited by the product, CTP. Mammalian cells defective in this allosteric inhibition are found to have a complex phenotype: They require thymidine in the growth medium, they have unbalanced nucleotide pools, and they have a mutator phenotype. Explain the basis for these observations.
Which ONE of these statements is the most accurate definition of the mode of action of imatinib? Select one: A.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks phosphatase activity by competing with adenosine triphosphate (ATP) binding B.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks tyrosine kinase activity by competing with adenosine triphosphate (ATP) binding C.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks tyrosine kinase activity by interaction with the enzyme site D.It is a specific inhibitor of the BCR‐ABL1 fusion protein and blocks phosphatase activity by interaction with the enzyme site
3) What specific proteins might be targeted for up- or downregulated adsorption when designing an implantable material? Please list at least two for each.
), create a simple flowchart depicting the MC1R pathway. There should be a minimum of five steps in the pathway. Be sure to include reception (protein binding to its ligand), a portion of the transduction pathway (what’s the intracellular reaction? What molecule works intracellularly?), and the cellular response (What’s produced from the cell?).
. Studies on CAMP actions in cultured cells usually involve adding to the cell culture not CAMP, but dibutyryl CAMP (see structure). Why is this structural modification necessary? How could you test the premise that di-Bu-CAMP has the same biochemical effects as CAMP? N. N= Nat Dibutyryl CAMP O
Describe the intracellular, biochemical downstream signal cascade that results from the binding of menthol to TRPM8
Describe the importance of ubiquitin-dependent degradation of soluble proteins.
Q1. Explain why GDP cannot dissociate from the alpha subunit of the Trimeric G-protein even though the receptor is activated by ligand binding and there is enough GTP for the exchange process.
Overall RNA metabolism and proteins involved are regulated by ubiquitin signaling. Explain how ubiquitination plays role in maintaining certain levels of proteins needed by including the process of protein degradation, ubiquitination, any enzymes, proteasome, any ATP hydrolysis. PLEASE do not provide me with a super long answer. Short and to the point would be greatly appreciated!!!!!
1 of 16 Data from an experiment is shown in the figure below. In the experiment, murine cells were treated with a specific a ligand that activates receptor R. In some cases, the cells were exposed to one of two drugs (X or Y) as well as the ligand or were left untreated (UT). After 30 minutes of treatment, the cells were lysed with a detergent-based buffer to release the soluble membrane, cyosolic and nuclear proteins. Samples from each cell extract were run (in duplicate) by SDS-PAGE (SDS-polyacrylamide gel electrophoresis) in order to separate the proteins by molecular mass (size). The separated proteins were then transferred to a nitrocellulose membrane which was then probed with different antibodies in a western blotting procedure to detect specific phosphorylated proteins or total proteins. If present in the cell extract, these proteins appear as a dark band in the relevant western blot image within the figure. Drug X Drug Y UT Ligand Ligand Ligand Western blotting antibodies…
