Pka signaling - Study guides, Class notes & Summaries

Receptors and Signaling, Protein Engineering Exam Questions With Verified Answers. What are the five characteristic features of signal transduction? - answer1. Specificity: a given stimulus triggers a specific response 2. Amplification: a small incoming signal causes a cascade that results in a large response 3. Modularity: different components can be mixed and matched to build a signaling pathway 4. Desensitization: the ability to turn a signaling pathway off 5. Integration: the ability...
