For clathrin coated vesicle trafficking: If another molecule was bound to the GTP pocket which could not hydrolyze GDP, what is the affect on the vesicles?
Describe the process of formation of a clathrin-coated vesicle on the plasma membrane during receptor mediated endocytosis.
1. Cytosolic G-proteins that bind to the neck of a clathrin-coated vesicle to help pinch it off from the donor membrane are called: A. SNARES B. Cargo C. Dynamin D. Adaptin E. RABs 2. Sodium ions are unable to pass through a potassium ion channel as a result of which of the following? A. Their charge B. The larger size of the Na+ atomic Radii relative to K+ C. Their inability to shed their sphere of hydration to pass through...
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...
Which of the following accurately describes a step in GTP-driven nuclear transport? GTP hydrolysis powers a membrane-bound transporter protein. GTP-bound cargo interacts specifically with the protein fibrils of the pore. Binding of Ran-GTP to the receptor releases the cargo protein. Ran-GDP escorts the nuclear receptor back to the cytosol.
What stages of transcription requires GTP hudrolysis? (Please specify which stages) What stages of translation requires GTP hydrolysis? (Please specify which stages, not how many GTP is used) Please list what statement applies to Intermediate filaments (IF), microtubules (MTs) or actin filaments (AF). Some statements may apply to more than one filament type. a) End is stabilized with a GTP-cap b) Polymerization occurs at the + end c) Filament does not have polar ends d) Motor proteins can move along...
Immunocytochemistry is the method of visualization of proteins in cells with the use of antibody that recognize specific molecules. Recently the visualization of these antibody-bound molecules is realized with the imaging of fluorescently-labeled antibodies against these receptors. Which type of microscopy would be used for this study? 0. Confocal microscopy O. Phase-contrast microscopy O. Differential interference contrast microscopy Electron phase-contrast microscopy You are working on a project that involves an imaging of rough endoplasmic reticulum shown here. What microscope was...
Which of the following statements about the role of the COPI or COPII proteins in vesicular transport is CORRECT? They pinch and fuse the membrane to allow separation of the vesicle from the rest of the membrane of the donor compartment. They increase the curvature of the membrane and form the vesicle from the donor compartment. They bind to the membrane of the target organelle/compartment to ensure delivery specificity. They regulate the fusion of the vesicle membrane with its target...
