WebMar 6, 2024 · The S1P that dissociates from plasma proteins or is released from erythrocytes (presumably via the S1P exporter Mfsd2b ) is hydrolyzed by the hepatocyte exofacial lipid phosphatase, Plpp3, and some of the sphingosine so formed is captured in hepatocytes by SphK-mediated phosphorylation that regenerates S1P. Because not all of … WebJul 28, 2024 · The intracellular levels of S1P are maintained constant by the activity of two enzymes, S1P phosphatase and S1P lyase, that degrade S1P. Whereas the degradation by S1P phosphatase leads to sphingosine and thus is reversible, the action of S1P lyase is irreversible, turning S1P into ethanolamine phosphate and hexadecenal. ...
