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 Magnesium-independent phospholipid phosphatase of the plasma membrane that catalyzes the dephosphorylation of a variety of glycerolipid and sphingolipid phosphate esters including phosphatidate/PA, lysophosphatidate/LPA, diacylglycerol pyrophosphate/DGPP, sphingosine 1-phosphate/S1P and ceramide 1-phosphate/C1P (PubMed:27694435, PubMed:9607309, PubMed:9705349). Also acts on N-oleoyl ethanolamine phosphate/N-(9Z-octadecenoyl)-ethanolamine phosphate, a potential physiological compound (PubMed:9607309). Has both an extracellular and an intracellular phosphatase activity, allowing the hydrolysis and the cellular uptake of these bioactive lipid mediators from the milieu, regulating signal transduction in different cellular processes (PubMed:23591818, PubMed:27694435, PubMed:9607309). Through the dephosphorylation of extracellular sphingosine-1-phosphate and the regulation of its extra- and intracellular availability, plays a role in vascular homeostasis, regulating endothelial cell migration, adhesion, survival, proliferation and the production of pro-inflammatory cytokines (PubMed:27694435). By maintaining the appropriate levels of this lipid in the cerebellum, also ensure its proper development and function (By similarity). Through its intracellular lipid phosphatase activity may act in early compartments of the secretory pathway, regulating the formation of Golgi to endoplasmic reticulum retrograde transport carriers (PubMed:23591818).FUNCTION Independently of this phosphatase activity may also function in the Wnt signaling pathway and the stabilization of beta-catenin/CTNNB1, thereby regulating cell proliferation, migration and differentiation in angiogenesis or yet in tumor growth (PubMed:20123964, PubMed:21569306). Also plays a role in integrin-mediated cell-cell adhesion in angiogenesis (PubMed:12660161, PubMed:16099422).CATALYTIC ACTIVITY a 1,2-diacyl-sn-glycero-3-phosphate + H2O = a 1,2-diacyl-sn-glycerol + phosphateCATALYTIC ACTIVITY 1,2-dihexadecanoyl-sn-glycero-3-phosphate + H2O = 1,2-dihexadecanoyl-sn-glycerol + phosphateCATALYTIC ACTIVITY 1,2-di-(9Z-octadecenoyl)-sn-glycero-3-phosphate + H2O = 1,2-di-(9Z-octadecenoyl)-sn-glycerol + phosphateCATALYTIC ACTIVITY a monoacyl-sn-glycero-3-phosphate + H2O = a monoacylglycerol + phosphateCATALYTIC ACTIVITY (9Z)-octadecenoyl-sn-glycero-3-phosphate + H2O = (9Z-octadecenoyl)-glycerol + phosphateCATALYTIC ACTIVITY sphing-4-enine 1-phosphate + H2O = sphing-4-enine + phosphateCATALYTIC ACTIVITY an N-acylsphing-4-enine 1-phosphate + H2O = an N-acylsphing-4-enine + phosphateCATALYTIC ACTIVITY N-(octanoyl)-sphing-4-enine-1-phosphate + H2O = N-octanoylsphing-4-enine + phosphateCATALYTIC ACTIVITY N-(9Z-octadecenoyl)-ethanolamine phosphate + H2O = N-(9Z-octadecenoyl) ethanolamine + phosphateACTIVITY REGULATION Magnesium-independent phospholipid phosphatase (PubMed:9705349). Insensitive to N-ethylmaleimide (PubMed:9705349). Inhibited by sphingosine, zinc ions and modestly by propanolol (PubMed:9705349).BIOPHYSICOCHEMICAL PROPERTIES Lipid metabolism; phospholipid metabolism.SUBUNIT Forms functional homodimers and homooligomers that are not required for substrate recognition and catalytic activity (PubMed:14725715). Can also form heterooligomers with other PLPP2 and PLPP3 (PubMed:18215144). Interacts with CTNND1; negatively regulates the PLPP3-mediated stabilization of beta-catenin/CTNNB1 (PubMed:20123964).INTERACTION Cycles between the endoplasmic reticulum and the Golgi.TISSUE SPECIFICITY Ubiquitously expressed (PubMed:12660161, PubMed:9305923). Highly expressed in heart and placenta (PubMed:9305923).INDUCTION By EGF, VEGF, FGF2 and phorbol myristate acetate (PMA).DOMAIN The integrin-binding motif mediates the binding to integrin alpha-5/beta-1 (ITGA5:ITGB1) and integrin alpha-V/beta-3 (ITGAV:ITGB3) and is required for the function in integrin-mediated cell-cell adhesion.DOMAIN The dityrosine basolateral targeting motif mediates localization to the basolateral membrane in polarized cells.PTM N-glycosylated (PubMed:9705349). Contains high-mannose oligosaccharides (PubMed:9705349).SIMILARITY Belongs to the PA-phosphatase related phosphoesterase family.
