You are in a research lab studying the function of the mutated form of a receptor called Protein X, which results in disruptive symptoms in human patients: extreme fatigue, low blood pressure, and dizziness among other symptoms that may be affecting the reproductive system. From detailed genetic studies, you have found that there is a mutation in the region where the Nuclear Localization Signal (NLS) of Protein X is, which may account for the symptoms seen in patients. What kind of receptor is Protein X most likely to be? Select one: O a. Steroid Family Receptor O b. GPCR Growth Hormone Receptor O d. Thyroid Hormone Receptor

Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.
