sphingosine-1-phosphate phosphatase 1

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).

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Sphingosine-1-Phosphate Phosphatase 1 (SGPP1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Sphingosine-1-Phosphate Phosphatase 1 (SGPP1) were tested on 3 different plates, 8 replicates in each plate.
