cAMP stands for cyclic adenosine monophosphate.
cAMP, or cyclic adenosine monophosphate, plays a crucial role as a second messenger in various biological processes. Its discovery in 1957 marked a significant milestone in understanding how cells communicate and respond to external signals.
Here's a breakdown of its significance:
- Second Messenger: cAMP relays signals received at the cell surface (e.g., by hormones) to intracellular targets, triggering a cascade of events.
- Universal Regulator: It's involved in regulating metabolism and gene expression across all life forms.
- Mechanism of Action: cAMP typically activates protein kinases, which then phosphorylate and regulate the activity of other proteins.
In essence, cAMP acts as an intermediary, translating external stimuli into appropriate cellular responses, making it a fundamental component of cell signaling pathways.
