Berthon A, Hannah-Shmouni F, Maria AG, Faucz FR, Stratakis CA. Cyclic di-AMP crystal structure DNA Methylation Profiling Reveals Prognostically Significant Groups in Pediatric Adrenocortical Tumors: A Report From the International Pediatric Adrenocortical Tumor Registry. It is one of many ubiquitous nucleotide second messengers including cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), guanosine pentaphosphate ((p)ppGpp), and cyclic di-GMP (c-di-GMP). Cyclic adenosine monophosphate (cAMP) is a second messenger used for intracellular signal induction. It is synthesized from adenosine triphosphate (ATP) by enzymes (g-proteins) that are attached to metabotropic receptors and become released when the receptor is activated. Mol Cell Endocrinol.  DacA requires a manganese or cobalt metal ion cofactor. Epub 2019 Apr 20. doi: 10.1177/2333794X17742748. J Clin Endocrinol Metab.

The whole-genome expression profile (WGEP) of normal (pooled) adrenals, PRKAR1A- (3) and GNAS-mutant (3) was studied. Studies have shown that bacterial mutant strains with low c-di-AMP levels lysed significantly faster than their parent strains. A, Functional analysis of whole-genome transcriptome profiling of PPNAD and adrenal masses harboring…, A, Basal and cAMP-stimulated PKA activity in PRKAR1A - and GNAS -mutant lesions.…, NLM Results: GImM is the phosphoglucosamine mutase enzyme that interconverts glucosamine-6-phosphate to glucosamine-1-phosphate to later form cell wall peptidoglycan and other polymers. | Cyclic AMP is the final common pathway for many of the body's receptor signalling systems, and a popular drug target. NIH Objective and design: How does cAMP/protein kinase A signaling lead to tumors in the adrenal cortex and other tissues? 2020 Jun 29;4(9):bvaa075. 2017 Jun;46(2):419-433. doi: 10.1016/j.ecl.2017.01.007. , Cell wall precursor, and thus peptidoglycan precursor, biosynthesis activity can also affect c-di-AMP levels in the cell. Please enable it to take advantage of the complete set of features! Genetics of Adrenocortical Development and Tumors. Cyclic di-AMP (also called c-di-AMP and c-di-adenosine monophosphate) is a second messenger used in signal transduction in bacteria and archaea. See this image and copyright information in PMC. c-di-AMP is a signaling nucleotide used in signaling pathways that trigger outputs by using receptor or target proteins to sense c-di-AMP concentrations in the cell. It should not be confused with 5'-AMP-activated protein kinase (AMP-activated protein kinase).
COVID-19 is an emerging, rapidly evolving situation. 2008 Oct;93(10):4135-40. doi: 10.1210/jc.2008-0631.

HHS This detection and activation pathway involves STING, TBK1, and IRF3. , In eukaryotic cells, c-di-AMP is sensed and subsequently elicits a type I interferon (IFN) response, leading to the activation of defense mechanisms against viral infection. | Eur J Endocrinol. 2019 Jul;191:105316. doi: 10.1016/j.jsbmb.2019.02.011. 2009 Jul;161(1):153-61. doi: 10.1530/EJE-09-0027. The nucleotide either binds to the helicase DDX41, which in turn activates the STING pathway, or directly binds to the STING protein. It is "cyclic" because two bonds between the phosphate group and the hydroxyl groups on the sugar create a little ring structure. 2011 Apr 10;336(1-2):162-8. doi: 10.1016/j.mce.2010.11.018. pApA is also involved in a feedback inhibition loop that limits GdpP gene-dependent c-di-AMP hydrolysis, leading to elevated c-di-AMP levels. It is a cyclic nucleotide, composed of a phosphate group, the sugar ribose, and adenine. The dinucleotide is also produced by numerous human pathogens, prompting the exploration of numerous c-di-AMP-regulating pathways both in humans and in bacteria. Epub 2009 May 8. , Cyclic di-AMP has also been linked to bacterial RNA synthesis inhibition.
Effects of cyclic AMP are mediated by activation of cyclic AMP-dependent protein kinase (PKA), which phosphorylates proteins to regulate their function or activity. Glob Pediatr Health. Genes related to the Wnt signaling pathway (CCND1, CTNNB1, LEF1, LRP5, WISP1, and WNT3) were overexpressed in PRKAR1A-mutant lesions. Wnt/beta-catenin and 3',5'-cyclic adenosine 5'-monophosphate/protein kinase A signaling pathways alterations and somatic beta-catenin gene mutations in the progression of adrenocortical tumors. Clipboard, Search History, and several other advanced features are temporarily unavailable. Epub 2010 Nov 25. J Endocr Soc. Regulation of c-di-AMP is critical because high c-di-AMP levels lead to abnormal physiology, growth defects, and reduced virulence in infection. 17q22-24 chromosomal losses and alterations of protein kinase a subunit expression and activity in adrenocorticotropin-independent macronodular adrenal hyperplasia. Listeria monocytogenes has demonstrated such an effect. Cyclic di-AMP is synthesized by a membrane-bound diadenylate cyclase (also called diadenylyl cyclase, CdA, and DAC) enzyme called CdaA (DacA).
Epub 2017 Feb 22. In contrast to c-di-GMP, another second messenger, cyclic AMP (cAMP), has been shown to positively control the expression of acute virulence factors in P. aeruginosa(27,–31). The overwhelming majority of benign lesions of the adrenal cortex leading to Cushing syndrome are linked to one or another abnormality of the cAMP or protein kinase pathway. , Cyclic di-AMP has been linked to fatty acid synthesis regulation in Myobacterium smegmatis, the growth of S. aureus in conditions of low potassium, the sensing of DNA integrity in B. subtilis, and cell wall homeostasis in multiple species. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway.  In some bacteria, loss of the phosphodiesterases that degrade c-di-AMP leads to cell death. Instead, cyclic AMP stimulates a protein kinase cascade that ultimately leads to a cellular response. Gaujoux S, Tissier F, Groussin L, Libé R, Ragazzon B, Launay P, Audebourg A, Dousset B, Bertagna X, Bertherat J. J Clin Endocrinol Metab. Clay MR, Pinto EM, Cline C, Tran QT, Lin T, Dyer MA, Shi L, Wu H, Pounds SB, Zambetti GP, Orr BA, Ribeiro RC. DacA condenses two ATP molecules to make c-di-AMP, releasing 2 pyrophosphates in the process. Abnormalities of cAMP signaling are present in adrenocortical lesions associated with ACTH-independent Cushing syndrome despite the absence of mutations in known genes.

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. c-di-AMP stimulates the production of (p)ppGpp, an alarmone involved in bacterial stringent response. 2017 Nov 21;4:2333794X17742748.
