Adenosine 3',5'-cyclic monophosphate

Cyclic AMP (cAMP) is a central second messenger in cell signaling, propagating signals from receptors to downstream pathways. It is generated from ATP by several adenylate cyclase enzymes, which are modulated by G protein-coupled receptors. cAMP activates protein kinase A and the exchange proteins activated by cAMP (Epac1 and Epac2), which are nucleotide exchange factors for the Rap family of GTPases. cAMP is degraded to AMP by cyclic nucleotide phosphodiesterases.

Cyclic adenosine monophosphate (cAMP, cyclic AMP or 3'-5'-cyclic adenosine monophosphate) is a second messenger important in many biological processes. cAMP is derived from adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway.

Cyclic AMP is a second messenger molecule comprised of an adenine ribonucleotide bearing a phosphate group bound to the oxygen molecules at the 3' and 5' positions of the sugar moiety. Cyclic AMP, which is synthesized from ATP by the intracellular enzyme adenylate cyclase, modulates the activity of several hormone-dependent signal transduction pathways.

3', 5'-Cyclic AMP, also known as cyclic AMP or camp, belongs to the class of organic compounds known as 3', 5'-cyclic purine nucleotides. These are purine nucleotides in which the oxygen atoms linked to the C3 and C5 carbon atoms of the ribose moiety are both bonded the same phosphorus atom of the phosphate group. 3', 5'-Cyclic AMP exists as a solid, slightly soluble (in water), and a moderately acidic compound (based on its pKa). 3', 5'-Cyclic AMP has been found throughout all human tissues, and has also been primarily detected in feces, urine, blood, and cerebrospinal fluid. Within the cell, 3', 5'-cyclic AMP is primarily located in the cytoplasm and golgi. 3', 5'-Cyclic AMP exists in all eukaryotes, ranging from yeast to humans. In humans, 3', 5'-cyclic AMP is involved in the dopamine activation OF neurological reward system pathway, the intracellular signalling through adenosine receptor A2B and adenosine pathway, the purine metabolism pathway, and the excitatory neural signalling through 5-HTR 4 and serotonin pathway. 3', 5'-Cyclic AMP is also involved in several metabolic disorders, some of which include the xanthinuria type I pathway, adenine phosphoribosyltransferase deficiency (aprt), molybdenum cofactor deficiency, and xanthine dehydrogenase deficiency (xanthinuria). Outside of the human body, 3', 5'-cyclic AMP can be found in a number of food items such as breadnut tree seed, fruits, european chestnut, and chinese cabbage. This makes 3', 5'-cyclic AMP a potential biomarker for the consumption of these food products.

3',5'-cyclic AMP is a 3',5'-cyclic purine nucleotide having having adenine as the nucleobase. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an adenyl ribonucleotide and a 3',5'-cyclic purine nucleotide. It is a conjugate acid of a 3',5'-cyclic AMP(1-).

Functions as a mediator of hormone-action for a variety of hormones such as epinephrine, glucagon and ACTH, q.q.v. Activates phosphorylation of proteins by protein kinases. Defined as a "second messenger" because of its response to hormones ("first messengers"). Converted from adenosine triphosphate (ATP) by the enzyme adenylate cyclase.
