Diacylglycerol (DAG) increases the activity of protein kinase C by increasing its affinity for Ca ++. Protein kinase C regulates target proteins by serine and threonine phosphorylation. Note that both IP 3 and DAG activate protein kinase C, but by different mechanisms.
Diacylglycerol - Basic Neurochemistry - NCBI Bookshelf. The formation of DAG can result in activation of protein kinase C (PKC), an enzyme that was first described in the late 1970s. At least ten isoforms of PKC, 70 to 80 kDa, may exist in mammalian tissues [25,26]. Four conserved (C) and five variable (V) regions can be discerned (Fig. 21-5).
Diacylglycerol (DAG) is an important lipid that both is an intermediate in lipid biosynthetic pathways and can act as a signaling lipid. The majority of signaling DAG is generated by hydrolysis of phosphatidylinositol-4,5-bisphosphate (PIP2) by the enzyme phospholipase C, but DAG can also be generated when phosphatidic acid phosphatases (PAPs) remove the …

Protein kinase CPKC enzymes in turn are activated by signals such as increases in the concentration of diacylglycerol (DAG) or calcium ions (Ca2+). Hence PKC enzymes play important roles in several signal transduction cascades....Protein kinase CIdentifiersCAS no.141436-78-4DatabasesIntEnzIntEnz view9 more rows
Diacylglycerol (DAG) is a key secondary lipid messenger for transducing signals downstream of many receptors expressed by hematopoietic cells. DAG has shown to be important in driving the activation, proliferation, migration, and effector function of adaptive and innate immune cells.Sep 7, 2016
Diacylglycerol is a precursor to triacylglycerol (triglyceride), which is formed in the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase.
Diacylglycerol is an essential second messenger in mammalian cells.
Diacylglycerols are also intermediates of the extracellular lipid metabolism. DAGs are generated in the process of food digestion as a result of TAG hydrolysis by specific lipases.
Acylglycerols are less dense than water and are water insoluble. In contrast, mono- and diacylglycerols are polar molecules due to their free hydroxyl groups; they have emulsifying power.
As nouns the difference between diglyceride and diacylglycerol. is that diglyceride is (chemistry) a lipid, an ester of glycerol and two fatty acids (the same or different, in the 1,2 or 1,3 positions) while diacylglycerol is (organic chemistry) diglyceride.
Summary. 1,2-Diacyl-sn-glycerol-3-phosphate, often referred to as phosphatidate, is a class of compounds consisting of a glycerol backbone, a (usually) saturated fatty acid bonded to carbon 1, a (usually) unsaturated fatty acid bonded to carbon 2, and a phosphate group esterified to carbon 3.

Examples of second messenger molecules include cyclic AMP, cyclic GMP, inositol triphosphate, diacylglycerol, and calcium. First messengers are extracellular factors, often hormones or neurotransmitters, such as epinephrine, growth hormone, and serotonin.
Scaffold proteins play key roles in providing a platform for signaling molecules to assemble, promoting the localization of signaling molecules at specific sites and coordinating positive and negative feedback signals for pathway regulation.
Second messengers are typically present at low concentrations in resting cells and can be rapidly produced or released when cells are stimulated.
