Chapter 9, Problem 12RQ

Histamine binds to the H1 G-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated G-protein’s alpha subunit prevented the hydrolysis of GTP how would the allergic response change?

  1. More severe allergic response compared to normal G-protein signaling.
  2. Less severe allergic response compared to normal G-protein signaling.
  3. No allergic response.
  4. No change compared to normal G-protein signaling.

Cholera toxins, produced by the pathogenic bacteria Vibrio cholerae, disrupt G Protein Coupled Receptor (GPCR) signaling pathways. They interfere with... the ability of the beta subunit of a G protein to bind to the GPCR  the ability of the gamma subunit of a G protein to exchange GDP for GTP  the ability of the beta subunit of a G protein to bind to an effector protein  the ability of the alpha subunit of a G protein to hydrolyze GTP to GDP
Compare and contrast signaling via G-protein coupled receptor, receptor tyrosine kinases, nuclear receptor. Please name at least one ligand/receptor for each pathway. Also describe the 'fast' and 'slow' responses mediated by ligand binding
The figure below shows a signaling pathway activated by the binding of adrenaline to the beta-adrenergic receptor. Binding of adrenaline to the receptor causes GTP-binding and activation of G proteins. Active GTP-boundG protein activates adenylate cyclase to initiate a signaling cascade that affects cellular responses, and includes cellular changes to mediate increased heart rate and accounts for the flight-or-fight response. activated adrenaline activated B-adrenergic receptor adenylate cyclase adenylate cyclase G protein subunit GTP 3. GDP conformational ATP CAMP change in receptor heterotrimeric G protein ACAMP inactive protein kinase A active protein kinase A cellular responses Consider the homozygous mutation in which a cell produces a variant of the adrenergic receptor that is constitutively active in the absence of ligand. Which of the following are true in this cell? Select all that apply. Protein Kinase A is always activated CAMP concentration is higher than normal Heart rate…
