Previous GeneCards Identifiers for SGPP1 Gene
Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite that regulates diverse biologic processes. SGPP1 catalyzes the degradation of S1P via salvage and recycling of sphingosine into long-chain ceramides (Mandala et al., 2000 [PubMed 10859351]; Le Stunff et al., 2007 [PubMed 17895250]).[supplied by OMIM, Jun 2009]

SGPP1 (Sphingosine-1-Phosphate Phosphatase 1) is a Protein Coding gene. Among its related pathways are Metabolism and Sphingolipid metabolism. Gene Ontology (GO) annotations related to this gene include sphingosine-1-phosphate phosphatase activity. An important paralog of this gene is SGPP2.
UniProtKB/Swiss-Prot for SGPP1 Gene
Specifically dephosphorylates sphingosine 1-phosphate (S1P), dihydro-S1P, and phyto-S1P. Does not act on ceramide 1-phoshate, lysophosphatidic acid or phosphatidic acid. Regulates the intracellular levels of the bioactive sphingolipid metabolite S1P that regulates diverse biological processes acting both as an extracellular receptor ligand or as an intracellular second messenger (PubMed:12815058, PubMed:11756451). Involved in efficient ceramide synthesis from exogenous sphingoid bases. Converts S1P to sphingosine, which is readily metabolized to ceramide via ceramide synthase. In concert with sphingosine kinase 2 (SphK2), recycles sphingosine into ceramide though a phosphorylation/dephosphorylation cycle. Regulates intracellular ceramide levels, which in turn regulate apoptosis (By similarity). Via S1P levels, modulates resting tone, intracellular Ca(2+) and myogenic vasoconstriction in resistance arteries (PubMed:18583713). Also involved in unfolded protein response (UPR) and ER stress-induced autophagy via regulation of intracellular S1P levels (PubMed:20798685).
