caffeine and theophylline inhibit cAMP phosphodiesterase, which degrades cAMP - thus enabling higher levels of cAMP than would otherwise be had. bucladesine (dibutyryl cAMP, db cAMP) - also a phosphodiesterase inhibitor; pertussis toxin, which increases cAMP levels by inhibiting Gi to its GDP (inactive) form. This leads to an increase in ...
cAMP represented in three ways Adenosine triphosphate. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger, or cellular signal occurring within cells, that is important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms ...
In cell biology, protein kinase A (PKA) is a family of serine-threonine kinase [1] 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.
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
The G s alpha subunit (G αs, G s α) is a subunit of the heterotrimeric G protein G s that stimulates the cAMP-dependent pathway by activating adenylyl cyclase.G s α is a GTPase that functions as a cellular signaling protein.
One example of crosstalk between proteins in a signalling pathway can be seen with cyclic adenosine monophosphate's (cAMP) role in regulating cell proliferation by interacting with the mitogen-activated protein (MAP) kinase pathway. cAMP is a compound synthesized in cells by adenylate cyclase in response to a variety of extracellular signals.
cAMP receptor protein (CRP; also known as catabolite activator protein, CAP) is a regulatory protein in bacteria. Protein. CRP protein binds cyclic adenosine ...
The Akt signaling pathway or PI3K-Akt signaling pathway is a signal transduction pathway that promotes survival and growth in response to extracellular signals. Key proteins involved are PI3K ( phosphatidylinositol 3-kinase ) and Akt ( protein kinase B ).
