1. NSF is an enzyme that uses the energy of ATP hydrolysis to disassemble complexes between v-SNAREs and t-SNAREs.a) Why do you suppose such an enzyme is needed?b) If NSF were suddenly inactivated and then the cells were examined a short time later, what types of effects would you expect to see?
Poliovirus is highly cytopathic both in cultured cells and in animals. Inoculation of mice with poliovirus leads to a robust antibody and cellular response. Explain why mice infected with a poliovirus mutant that cannot cause cell death have poor antibody and cellular responses. What would be one strategy to restore robust antibody and cellular responses in mice infected with this mutant virus?
Which of the following protein domains would you expect to find in an "easily druggable" target but
NOT in an "undruggable" target. An easily druggable target is defined as a target with an easily
accessible active site than can be activated or inhibited. Please Explain.
Answer Choices:
A) Extracellular domain
B) Intracellular domain
C) Membrane Spanning domain
D) ATP-binding domain
E) Protein Binding domain

- Naive T cells are isolated and left untreated or treated with ‘compound X’ for 1 hour. Following this, the T cells are incubated with a range of concentrations of a soluble form of ICAM-1 that has been conjugated to a fluorescent dye (soluble-ICAM-1-FITC). Fifteen minutes later, the cells are washed, and the relative amount of fluorescence bound to the cells is measured. The results of this assay are shown in the figure below. The most likely identity of compound X is: The adhesion molecule, LFA-1 The adhesion molecule, L-selectin The sulfated carbohydrate structure, sulfated sialyl-LewisX The chemokine ligand for CCR7 The immunoglobulin superfamily member, CD2arrow_forwardHow are targeting and fusionproteins such as SNAREs regulated,so that they can be returned to theirrespective donor compartments in aninactive state?arrow_forward135.
