Application Abreviews Notes
  • Application notes
    WB: Use at a concentration of 1 µg/ml. Detects a band of approximately 52 kDa (predicted molecular weight: 52 kDa).
    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function

      Esterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate, an essential step in glycerolipid biosynthesis. Active against both saturated and unsaturated long-chain fatty acyl-CoAs.
    • Tissue specificity

      Ubiquitous. Relatively high level of expression in skeletal muscle, heart and testis. Relatively low level of expression in lung.
    • Pathway

      Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
    • Sequence similarities

      Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
    • Domain

      The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate.
    • Cellular localization

      Endoplasmic reticulum membrane.

    • Anti-GPAT4 antibody (ab76707) at 1 µg/ml + Human skeletal muscle tissue lysate - total protein (ab29330) at 10 µg

      Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 52 kDa
      Observed band size: 49 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 30 kDa. We are unsure as to the identity of these extra bands.

      Exposure time: 10 minutes

      The band observed at 49 kDa could potentially be a cleaved form of Human 1-acyl-sn-glycerol-3-phosphate acyltransferase zeta precursor (AGPAT6). The protein contains a 36 amino acid signal peptide, which when cleaved gives an expected molecular weight of 48 kDa.
