- Endothelins are 21-amino acid vasoconstricting peptides produced primarily in the endothelium. They have an important role in vascular homeostasis. Endothelin activates G protein-coupled receptors (GPCRs) ETA or ETB on a target cell. Which subunit of heterotrimeric G protein is released when the receptor is activated? a.) gamme b.) beta c.) alphaThe Structure of the acetylcholine receptor is shown below: A. Knowing the amino acid sequence of this protein, what tool would you use to identify the membrane-spanning region? Explain how it works.Endocrine Ligand acting on intracellular receptor should be: O Hydrophilic O Hydrophobic O Amphipathic O Macromolecule What kinds of molecules may pass through

Activates other proteins Activates vi which then phosphorylates other intracellular targets. form complex with vii.AMPK and mTOR can both be considered intracellular signal integrators. Explain this definition.When you think about the primary structure of the mannose-6-P receptor, assuming that it is an integral membrane protein with one membrane-spanning domain and assuming that it has a ERSS, what are all of the different protein domains that must be present in this protein's primary structure to get it to where it needs to go and to carry out all of the functions/activities? (Draw a schematic of the protein structure/sequence and explain each region). What do you think would happen to a soluble protein that normally contains a KDEL tag (ER retrieval) if the tag was cleaved off (where would the protein end up)?
- Ligand binding to proteins may occur with varying strengths; some ligands bind tightly to proteins while others bind less tightly. The strengths of reversible binding are determined experimentally by varying concentrations of ligands, and measuring the saturation of the protein in the various ligand concentrations. One such laboratory study investigated the binding of a hormone to three different receptor proteins in the cell membrane. The data collected are shown in the table below 1) Which of the proteins demonstrate the tightest/strongest binding of the hormone? Which demonstrates the least tight binding of the hormone? What is the basis for your answer?Item21 Item 21 Neurons have a _______ membrane potential of –70mV. In other words, this is their stable membrane potential under normal conditions.
