Common NameCerP(d18:1/18:0)
DescriptionCerP(d18:1/18:0), also known as N-octadecanoyl-sphing-4-enine-1-phosphate, is a ceramide phosphate (CerP). Ceramide phosphates are members of the class of compounds known as sphingolipids (SPs), or glycosylceramides. SPs are lipids containing a backbone of sphingoid bases (e.g. sphingosine or sphinganine) that are often covalently bound to a fatty acid derivative through N-acylation. SPs are found in cell membranes, particularly in peripheral nerve cells and the cells found in the central nervous system (including the brain and spinal cord). Sphingolipids are extremely versatile molecules that have functions controlling fundamental cellular processes such as cell division, differentiation, and cell death. Impairments associated with sphingolipid metabolism are associated with many common human diseases such as diabetes, various cancers, microbial infections, diseases of the cardiovascular and respiratory systems, Alzheimer’s disease and other neurological syndromes. The biosynthesis and catabolism of sphingolipids involves a large number of intermediate metabolites where many different enzymes are involved. Simple sphingolipids, which include the sphingoid bases and ceramides, make up the early products of the sphingolipid synthetic pathways, while complex sphingolipids may be formed by the addition of head groups to the ceramide template (Wikipedia). In humans, ceramide phosphate are formed from ceramides by the action of a specific ceramide kinase (CerK) and can be dephosphorylated by phosphatidate phosphatase back to the ceramide. CerPs are an important metabolite of ceramide as it acts as a mediator of the inflammatory response. CerPs are also known to have a dual regulatory capacity acting as intracellular second messengers to regulate cell survival, or as extracellular receptor ligands to stimulate chemotaxis. Moreover, CerPs have been shown to be specific and potent inducers of arachidonic acid and prostanoid synthesis in cells through the translocation and activation of cytoplasmic phospholipase A2. In terms of its appearance and structure, CerP(d18:1/18:0) is a colorless solid that consists of an unsaturated 18-carbon sphingoid base with an attached saturated octadecanoyl fatty acid side chain. In most mammalian SPs, the 18-carbon sphingoid bases are predominant (PMID: 9759481 ).

Enzymes

General function:
Not Available
Specific function:
Magnesium-independent phospholipid phosphatase that catalyzes the dephosphorylation of a variety of glycerolipid and sphingolipid phosphate esters including phosphatidate/PA, lysophosphatidate/LPA, sphingosine 1-phosphate/S1P and ceramide 1-phosphate/C1P. Has no apparent extracellular phosphatase activity and therefore most probably acts intracellularly. Also acts on N-oleoyl ethanolamine phosphate/N-(9Z-octadecenoyl)-ethanolamine phosphate, a potential physiological compound. Through dephosphorylation of these bioactive lipid mediators produces new bioactive compounds and may regulate signal transduction in different cellular processes (By similarity). Indirectly regulates, for instance, cell cycle G1/S phase transition through its phospholipid phosphatase activity (By similarity).
