13. a) activate MAP (mitogen activated protein) kinase module containing three protein kinases.
Ras a protein is tethered to plasma membrane by causing it to bind GTP. Once acivated can do variety of things such as it activates the enzymatic cascade of MAP kinase, which results in potent change in the cell.
on the type of cell resulting in new gene e enters the nucleus and activates specifie...
The GTPase Dynamin is involved in which step of vesicular A) Binding of cargo molecules to cargo receptors B) Assembly of the Clathrin coat C) Pinching off the vesicle from the membrane D) Transport of vesicles along microtubules Which of the following events does not occur in the rough endoplasmic reticulum? A) Cleavage of the signal peptide by the signal peptidase B) Binding of chaperone proteins to misfolded or partially folded pathways C) Transfer of a pre formed oligosaccharide to...
23. A protein called Ras is tethered (linked) to the plasma membranes of stem cells where it participates in signal transduction pathways that affect stem cell proliferation. Which of the following covalent modifications would be responsible for tethering (linking) the Ras to the membrane? A. Phosphorylation B. Glycosylation C. Lipid modification D. Ubiqutiylation E. Acetylation 24. What do transmembrane proteins in the peroxisome, nucleus, and mitochondria all have in common? A. They are all co-translationally inserted into the membrane B....
21: Met c aion of the Polamino 21. Which of the following would NOT Change the structure and function of a protein A Methylation of a protein B. Lipid modification of a protein C. Change in the length of the Poly A tail of the mRNA transcript encoding a protein D. Change in the position of reactive amino acids E. Proteolysis 22. Two peptides have almost the exact same primary structure, except that one has about 10 fewer amino acids...
