Insights

Ceramide kinase (CERK) and its product ceramide-1-phosphate (C1P) are involved in inflammation, immunity, and cancer. This review overviews C1P biosynthesis and its role in activating cPLA2alpha for eicosanoid synthesis.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Molecular Biology

Background:

  • Ceramide kinase (CERK) has been studied for over a decade.
  • CERK plays roles in inflammation, immunity, and cancer signaling pathways.
  • Ceramide-1-phosphate (C1P) is a key product of CERK activity.

Purpose of the Study:

  • To review the biosynthesis of ceramide-1-phosphate (C1P).
  • To overview the biological roles of CERK and C1P.
  • To focus on C1P's role in eicosanoid synthesis via cPLA2alpha activation.

Main Methods:

  • Literature review of published reports on CERK and C1P.
  • Analysis of signaling pathways involving CERK and C1P.
  • Discussion of therapeutic implications.

Main Results:

  • CERK produces C1P, a lipid mediator.
  • C1P is involved in activating cytosolic phospholipase A2-alpha (cPLA2alpha).
  • Activation of cPLA2alpha by C1P influences eicosanoid synthesis.

Conclusions:

  • CERK and C1P are significant in cellular signaling.
  • C1P's role in cPLA2alpha activation is crucial for eicosanoid production.
  • Inhibitors targeting these pathways may have therapeutic potential.

cAMP-dependent Protein Kinase Pathways

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,...
Anaphase Promoting Complex00:50

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

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,...
Intracellular Signaling Cascades01:24

Intracellular Signaling Cascades

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

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 produces two-second...
