Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Has specific phosphohydrolase activity towards sphingoid base 1-phosphates. Has high phosphohydrolase activity against dihydrosphingosine-1-phosphate and sphingosine-1-phosphate (S1P) in vitro (PubMed:12411432). Sphingosine-1-phosphate phosphatase activity is needed for efficient recycling of sphingosine into the sphingolipid synthesis pathway (By similarity). May play a role in attenuating intracellular sphingosine 1-phosphate (S1P) signaling. May play a role in pro-inflammatory signaling (PubMed:17113265). Plays a role in the regulation of pancreatic islet beta-cell endoplasmic reticulum stress and proliferation (By similarity).CATALYTIC ACTIVITY sphinganine 1-phosphate + H2O = sphinganine + phosphateCATALYTIC ACTIVITY sphing-4-enine 1-phosphate + H2O = sphing-4-enine + phosphateCATALYTIC ACTIVITY (4R)-hydroxysphinganine 1-phosphate + H2O = (4R)-hydroxysphinganine + phosphateSUBCELLULAR LOCATION Expressed strongly in kidney and heart, followed by brain, colon, small intestine and lung. Not detected in skeletal muscle, thymus, spleen, liver, placenta, and peripheral blood leukocytes.INDUCTION Strongly induced by TNF, also induced by bacterial lipopolycaccharides (LPS) in neutrophils, endothelial cells, and other cell types. Not induced by growth-related factors.SIMILARITY Belongs to the type 2 lipid phosphate phosphatase family.
