Describe two features of insulin signaling that affect glucose utilization. A b -adrenergic response can be modulated through the actions of a receptor kinase and arrestin, because phosphorylation by the kinase desensitizes the receptor. How might signaling by a tyrosine receptor kinase, such as the insulin receptor, be modulated?
