<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Catalyzes the phosphorylation of sphingosine to form sphingosine-1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on D-erythro-dihydrosphingosine, D-erythro-sphingosine and L-threo-dihydrosphingosine. Binds phosphoinositides (PubMed:16118219, PubMed:10751414). In contrast to prosurvival SPHK1, has a positive effect on intracellular ceramide levels, inhibits cells growth and enhances apoptosis (PubMed:16118219). In mitochondria, is important for cytochrome-c oxidase assembly and mitochondrial respiration. The SPP produced in mitochondria binds PHB2 and modulates the regulation via PHB2 of complex IV assembly and respiration (PubMed:20959514). In nucleus, plays a role in epigenetic regulation of gene expression. Interacts with HDAC1 and HDAC2 and, through SPP production, inhibits their enzymatic activity, preventing the removal of acetyl groups from lysine residues with histones. Upregulates acetylation of histone H3-K9, histone H4-K5 and histone H2B-K12. In nucleus, may have an inhibitory effect on DNA synthesis and cell cycle (By similarity). In mast cells, is the main regulator of SPP production which mediates calcium influx, NF-kappa-B activation, cytokine production, such as TNF and IL6, and degranulation of mast cells (PubMed:17346996). In dopaminergic neurons, is involved in promoting mitochondrial functions regulating ATP and ROS levels (PubMed:25637806). Also involved in the regulation of glucose and lipid metabolism (PubMed:30593892).By similarity6 Publications

Mutant mice are viable, fertile and have normal longevity. They show reduced SPP levels (PubMed:16314531). Mice have decreased fat mass but increased lean mass, they display increased energy expenditure compared to wild-type. Aging mice are protected from metabolic decline and obesity. 52-week old male mutant mice have decreased weight and fat mass, and increased glucose tolerance and insulin sensitivity compared to control mice (PubMed:30593892). Double knockout for SPHK1 and SPHK2 causes embryonic lethality (PubMed:16314531). Between 11.5 dpc and 12.5 dpc embryos exhibit cranial hemorrhage and die at 13.5 dpc (PubMed:16314531). At 11.5 dpc the wall of the dorsal aorta is poorly developed and endothelial cells are severely defective in all blood vessels in the mesenchymal region of the head (PubMed:16314531). Embryos also show a neural tube defect (PubMed:16314531).2 Publications

Annotation score:1 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

<p>This subsection of the ‘Sequence’ section reports difference(s) between the canonical sequence (displayed by default in the entry) and the different sequence submissions merged in the entry. These various submissions may originate from different sequencing projects, different types of experiments, or different biological samples. Sequence conflicts are usually of unknown origin.<p><a href='/help/conflict' target='_top'>More...</a></p>Sequence conflicti252N → S in AAF74125 (PubMed:10751414).Curated1

<p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called ‘Primary (citable) accession number’.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: Q9JIA7
Secondary accession number(s): Q91VA9, Q9DBH6
<p>This subsection of the ‘Entry information’ section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification (‘Last modified’). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical_and_isoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: October 24, 2001
