Intercellular signaling by growth factors, hormones and neurotransmitters produces second messenger molecules such as cyclic adenosine monophosphate (cAMP) and diacylglycerol (DAG). Protein Kinase A and Protein Kinase C are the principal effector proteins of these prototypical second messengers in certain ...

Roles of Lipid Second Messengers and Their Modulators in the Molecular Pathogenesis of Hypertension 来自 openthesis.org 喜欢 0 阅读量: 16 作者:B Wu,Huanpin 摘要: The phospholipid PI(3,4,5)P3 works as a second messenger in PI3K signaling pathway. The PI3K signaling pathway is involved in ...
The role of lipid messengers such as diacylglycerol (DAG), PA, and phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2] levels are key components in the fly phototransduction process (49, 50, 51). Experimental evidence from previous research using the visual signaling pathway as a model system ...
The role of the phosphatidylinositol transfer protein and phospholipase D in signal transmission, and the structures of the 1,2-diacylglycerol and calcium-binding sites of protein kinase C are discussed. Further, ceramide signaling through protein kinases and the role of cross-talk in the signaling...
Second messenger systems are complex and intersect in a variety of different pathways. The regulation of these signaling molecules is equally complex and not yet fully understood. The enzymes that produce them and the regulation of “first messengers” that initiate a second messenger cascade represent...
Summary Second messengers are key components of many signal transduction pathways. In addition to cyclic AMP, ppGpp and cyclic di-GMP, many bacteria use also cyclic di-AMP as a second messenger. This molecule is synthesized by distinct classes of diadenylate cyclases and degraded by phosphodiester...
