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.
Homework Answers
Which of the following accurately describes a step in GTP driven nuclear transport?
Binding of Ran-GTP to the receptor releases the cargo protein.
In cytoplasm cargo protein binds to the receptor and move to the nucleus, in nucleus interaction of Ran-GTP causes conformational changes and Cargo proteins dissociates from the receptor.
Nuclear receptor get back to the cytosol but it back with the Ran-GTP.

Ran is a GTPase. Ran in the GTP bound form is concentrated in the nucleus while Ran in the GDP bound form is concentrated in the cytosol. This compartmentalization of Ran-GTP versus Ran-GDP is essential for nuclear-cytosolic protein transport. Please select which of the following statements best describes how the Ran-GTP/Ran GDP gradient is established. Select one: 1. It's another trick question. Ran has nothing to do with nuclear import. Ran is for signaling purposes. The small GTPase, Ras, drives...

1) how does the timing and location of Arf1-GTP hydrolysis contribute the transport of COPI coated vesicles? 2) Consider cargo proteins that are destined for secretion to the extracellular space. For each of the following pairs of mutations or conditions, predict where the cargo will end up (ex. in the cytoplasm, a specific organelle, transport vesicles, multiple places, extracellular space) for: (i) & (ii) Each individual condition; & (iii) The combination of both. A.(i) Normal Sar1 is mutated so that...

Hagrid has purified a protein from unicom sweat and called UNI-1. He has then doned the Unit gone and inserted in rat zygotes (by microinjection) a recombinant construct containing the Uni-1 coding sequence its entire 5 UTR region, covering both the minimal promoter and a series of cutative regulatory als elements. The mutantrats develop glorious, luminous hair. Hagrid has also discovered that the UNI-1 protein binds very tightly to DNA and hypothesizes it is a transcription factor that regulates proliferation...
