  • Function
    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-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol.
  • Tissue specificity
    Widely expressed with highest levels in adult liver, kidney, heart and skeletal muscle.
  • Sequence similarities
    Contains 1 DAGKc domain.

  • ICC/IF image of ab37980 stained HepG2 cells. The cells were 4% Formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab37980, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 Goat anti-Rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    All lanes : transfected 293 cell lysate

    Predicted band size: 42 kDa
    Observed band size: 47 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 200 kDa. We are unsure as to the identity of these extra bands.

Thank you for your email.

Yes, I meant His or GST tag etc.

It is more likely that the band appeared in SPHK2 blot is the specific one. However it can be further testified by
- trying no primary control.
- blocking the antibody...
