The insulin receptor is an example of a:
| A. |
GPCR. |
|
| B. |
JAK-STAT receptor. |
|
| C. |
receptor tyrosine kinase. |
|
| D. |
All of the above. |
|
| E. |
A and B. |
Tha answer is C. Insulin receptor is alarge class of tyrosine kinase recptor. Janus kinase (JAK-STAT) is a cytokine receptor.
The insulin receptor is an example of a: A. GPCR. B. JAK-STAT receptor. C. receptor tyrosine...
Match the abbreviation with its full name. GPCR A. Mitogen-activated protein kinases RTK B. Non-receptor tyrosine kinase v NRTK C. G-protein coupling receptor MAPK D. Receptor tyrosine kinase
Insulin signalling acts through an insulin receptor, which is a receptor tyrosine kinase (TRUE OR FALSE?)
Explain the difference between amplification of signal by a tyrosine receptor kinase and a GPCR. Explain what would happen if you increased expression of a phosphatase or phosphodiesterase in each situation respectively.
You have developed an activator of a non-receptor tyrosine kinase. In three different cell types that all contain this receptor your drug has different effects. In cell type A you see activation of gene X and gene Y; in cell type B you note activation of Gene X, but no change in the mRNA levels for Gene Y. In cell type C your drug has no effect on either Gene X or Y. Describe how could each choice (A-D) be...

Which of the following signaling molecule function via JAK kinase and transcriptional regulatory protein STAT? Group of answer choices a. Ethylene oxide b. Prolactin c. TGF β d. EGF e. All of the above
Insulin binds to a receptor that_ I. is coupled to a G protein II. possesses tyrosine kinase activity III. possesses serine/threonine phosphatase activity IV. interacts with proteins such as IRS-1 I, IV I, III II, IV Oll only I, II, III
You
perform an assay on the activity of the JAK tyrosine kinase using a
40 microliter aliquot of a lysate prepared from cells labeled for
six minutes with radioactive cysteine. the total volume of the
lysate is 5 milliliters (ml). In the aliquot, you measure the
amount of all proteins and determine the presence of 13 micrograms
of protein in 75 microliters of lysate. which of the following is
the best calculation of the specific activity of the kinase in...
Which of the following are NOT TRUE about tyrosine kinase-associated receptors? a. they bind to tyrosine kinases b. the alpha interferon receptor is an example of a tyrosine kinase-associated receptor. c. ligand binding results in phosphorylation of the cytoplasmic tails of the receptors on tyrosines d. they have tyrosine kinase domains
