Textbook Question
Chapter 12, Problem 12.4PS
Coated Vesicles in Intracellular Transport. For each of the following statements, indicate for which coated vesicle the statement is true: clathrin- (C), COPI- (I), or COPII-coated (II). Each statement may be true for one, several, or none (N) of the coated vesicles discussed in this chapter.
(a) Binding of the coat protein to an LDL receptor is mediated by an adaptor protein complex.
(b) Fusion of the vesicle (after dissociation of the coat) with the Golgi membrane is facilitated by specific t-SNARE and Rab proteins.
(c) Has a role in bidirectional transport between the ER and Golgi apparatus
(d) Has a role in sorting proteins for intracellular transport to specific destinations
(e) Has a role in transport of acid hydrolases to late endosomes
(f) Is essential for all endocytic processes
(g) Is important for retrograde traffic through the Golgi apparatus
(h) Is involved in the movement of membrane lipids from the TGN to the plasma membrane
(i) The basic structural component of the coat is called a triskelion.
(j) The protein coat dissociates shortly after formation of the vesicle.
(k) The protein coat always includes a specific small GTP-binding protein.

6. The figure above shows a model of a ligand precursor being cleaved to produce an active
ligand that binds to a specific receptor. Which of the following is most likely to reduce the
binding of the active ligand to its receptor?
(A) A change in the cytoskeletal attachment of transmembrane proteins
(B) The presence of a large amount of the precursor form of the ligand
(C) An increase in the ratio of the number of unsaturated to the number of saturated
fatty acid tails of the membrane lipids
(D) A mutation in the receptor gene that causes a substitution of a charged amino acid for a
nonpolar amino acid in the ligand binding site of the receptor

Short peptides such as legumain stabilization and activity modulation (LSAM) domain and αvβ3 integrin could enhance the activity of AEP. LSAM domain known as the prodomain of AEP blocks substrate binding before activation. This prodomain has a helical structure and two independent peptides. One is an activation peptide (AP, K287 to N323), and the other is a LSAM domain. LSAM domain remains even after AP is cleaved and released from protease at neutral pH via electrostatic interaction. AEP without LSAM domain has a lower melting temperature than AEP with LSAM domain [77, 117]. Another short peptide, αvβ3 integrin, can directly interact with AEP, and after forming a complex, the optimal pH for AEP activity is increased from 5.5 to 6.0. It indicates that αvβ3 binding could induce conformational stabilization of AEP accompanied by deprotonated C189. αvβ3 does not directly interact with the AEP active site; however, AEP docks to the αvβ3 RGD-binding site…arrow_forward
