Cyclic AMP (cAMP) Deranged Physiology

WebThe unique characteristic of protein kinase A is that its activity is regulated by fluctuating levels of cyclic AMP within cells (hence its alias as the cyclic AMP-dependent protein kinase). This enzyme thus functions as the end effector for a variety of hormones that work through a cyclic AMP signalling pathway. WebIn cell biology, protein kinase A ( PKA) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP). PKA is also known as cAMP-dependent protein kinase ( EC 2.7.11.11 ). PKA has several functions in the cell, including regulation of glycogen, sugar, and lipid metabolism. film michael raineyWebActivation of receptors can trigger the synthesis of small molecules called second messengers, which initiate and coordinate intracellular signaling pathways.

"WebTo analyze the molecular changes in signaling pathways that elicit different responses, we focused on the interaction between cyclic AMP (cAMP) and growth factors. We show that the activation of extracellular signal-regulated kinase 5 (ERK5), but not ERK1/2, by growth factors is disrupted by cAMP through cAMP-dependent protein kinase (PKA).

WebHowever, the Ca(2+) signal does not work in strict isolation, but rather is fine-tuned by many other signals, not the least of which is the other major second messenger, cyclic AMP (cAMP). Conversely, the cAMP pathway is subject to modification by the calcium signal and its various effectors at many different levels. WebActivation of receptors can trigger the synthesis of small molecules called second messengers, which initiate and coordinate intracellular signaling pathways. For example, …
