Summary
Cyclic pyrimidine nucleotides, cytidine 3
Area of Science:
- Biochemistry
- Cellular Biology
- Molecular Biology
Background:
- Cyclic pyrimidine nucleotides, cytidine 3',5'-cyclic monophosphate (cCMP) and uridine 3',5'-cyclic monophosphate (cUMP), have been identified in mammalian cells.
- These molecules are increasingly recognized for their roles in cellular signaling pathways.
Framework:
- The study discusses generators, effectors, biological functions, and inactivation mechanisms of cCMP and cUMP.
- Pseudomonas aeruginosa nucleotidyl cyclase toxin ExoY, a producer of cUMP, was a key focus.
Implementation:
- Advanced mass spectrometry methods were employed for the unequivocal identification of cCMP and cUMP.
- Expert discussions centered on the emerging field of noncanonical cyclic nucleotides.
Implications:
- cCMP and cUMP meet the criteria for second messengers, suggesting significant roles in cellular regulation.
- Future research will explore effector proteins, bacterial toxins, new model organisms (e.g., zebrafish), and other cyclic nucleotides like inosine 3',5'-cyclic monophosphate (cIMP).

01:12What are Second Messengers?
93.3K
Because many receptor binding ligands are hydrophilic, they do not cross the cell membrane and thus their message must be relayed to a second messenger on the inside. There are several second messenger pathways, each with their own way of relaying information. G-protein coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol path is active when the receptor induces phospholipase C to hydrolyze the phospholipid,...

Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...

7.2K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

9.5K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

01:11IP3/DAG Signaling Pathway
16.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...
