  • Immunofluorescence staining of HepG2 cells with CSB-PA751012LA01HU at 1:200, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

Function
Choline-specific phosphodiesterase that hydrolyzes sphingomyelin releasing the ceramide and phosphocholine and therefore is involved in sphingomyelin digestion, ceramide formation, and fatty acid (FA) absorption in the gastrointestinal tract. Has also phospholipase C activity and can also cleave phosphocholine from palmitoyl lyso-phosphatidylcholine and platelet-activating factor (PAF) leading to its inactivation. Does not have nucleotide pyrophosphatase activity. May promote cholesterol absorption by affecting the levels of sphingomyelin derived from either diet or endogenous sources, in the intestinal lumen.
Gene References into Functions
  1. human alkaline sphingomyelinase crystal structure provides insights into substrate recognition PMID: 28292932
  2. NPP7 activity and the ratio of 1.4/1.2 kb products in bile are significantly decreased in malignancy, particularly in cholangiocarcinoma. PMID: 25100243
  3. The F275A mutation of NPP7 showed impaired catalytic function whereas L107F mutation showed enhanced catalytic activity. PMID: 22177013
  4. predict the three-dimensional structure of NPP7 by homology modeling using a recently crystallized NPP from bacteria. Using the model, we studied the substrate specificity of the enzyme by docking. PMID: 20839774
  5. identified the amino acid and cDNA sequences of human intestinal alk-SMase, and found that it is a novel ecto-enzyme related to the ecto-nucleotide phosphodiesterase family with specific features essential for its SMase activity PMID: 12885774
  6. intestinal alkaline sphingomyelinase may have a one-exon deletion in colon cancer cells PMID: 15016655
  7. alk-SMase activity is severely affected by defective N-glycosylation at 5 sites and by structural alterations of the putative metal-binding sites and the predicted active core. PMID: 15458386
  8. Results describe the cloning of rat alkaline sphingomyelinase from rat intestine, comparison to the human sequence, adjustment of the putative protein in GenBank, and confirmation of the specific expression of the gene in the small intestine. PMID: 15708357
  9. Alkaline sphingomyelinase hydrolyses and inactivates PAF by a phospholipase C activity, a novel function by which it may counteract the development of intestinal inflammation and colon cancer. PMID: 16255717
