Explore the fundamental mechanisms that control cellular signaling pathways in this 31-minute lecture from NPTEL-NOC IITM. Delve into the three primary modes of regulation that govern how cells communicate: modification, inhibition, and activation of signaling components. Learn how receptors detect and respond to external signals, understand the role of various signaling molecules in transmitting information, and discover how effector proteins execute cellular responses. Examine the sophisticated regulatory networks that ensure proper signal transduction, including post-translational modifications that fine-tune protein function, inhibitory mechanisms that prevent unwanted signaling, and activation processes that amplify cellular responses. Gain insights into how these regulatory modes work together to maintain cellular homeostasis and enable appropriate responses to environmental changes.
