  • Function

    Serine palmitoyltransferase (SPT). The heterodimer formed with LCB1/SPTLC1 constitutes the catalytic core. The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference. The SPTLC1-SPTLC3-SSSPTA isozyme uses both C14-CoA and C16-CoA as substrates, while the SPTLC1-SPTLC3-SSSPTB has the ability to use a broader range of acyl-CoAs without apparent preference.
  • Tissue specificity

    Expressed in most tissues, except peripheral blood cells and bone marrow, with highest levels in heart, kidney, liver, uterus and skin.
  • Pathway

    Lipid metabolism; sphingolipid metabolism.
  • Sequence similarities

    Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
  • Cellular localization

    Endoplasmic reticulum membrane.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) staining human prostate cancer using ab237532 at 1/100. 
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) staining human colon cancer using ab237532 at 1/100. 

  • Paraffin-embedded human liver cancer tissue stained for SPTLC3 using ab237532 at 1/300 dilution in immunohistochemical analysis.

    After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30 minutes at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized tissue using an HRP conjugated SP system.

  • HepG2 (Human liver hepatocellular carcinoma cell line) cells stained for SPTLC3 (green) using ab237532 at 1/100 dilution in ICC/IF. Secondary antibody is an Alexa-Fluor® 488-conjugated Goat Anti-Rabbit IgG (H+L).
