Application Abreviews Notes
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 40, 55 kDa (predicted molecular weight: 39 kDa).


  • Function
    Acts as a receptor for L-lactate and mediates its anti-lipolytic effect through a G(i)-protein-mediated pathway.
  • Tissue specificity
    Expressed abundantly in brown and white fat. It also detectable at lower levels in liver, kidney, skeletal muscle, brain and pituitary. Not detected in frontal, temporal and occipital lobes of the cortex, basal forebrain, caudate nucleus, nucleus accumbens and hippocampus.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization
    Cell membrane.
  • Information by UniProt
  • Database links
  • Form
    G protein-coupled receptors (GPCRs, or GPRs), such as GPR81, contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.

  • Anti-GPCR GPR81 antibody (ab106942) at 0.5 µg/ml + Human liver lysate at 35 µg
    Developed using the ECL technique

    Predicted band size : 39 kDa
    Observed band size : 40 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 55 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 1 hourAn additional band of unknown identity was also consistently observed at 55 kDa. This band was successfully blocked by incubation with the immunizing peptide.
