Our Abpromise guarantee covers the use of ab42114 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB 1/1000 - 1/15000. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).Can be blocked with Dopamine Receptor D3 peptide (ab128688).
ELISA 1/50000.
Dot blot 1/50000.
IP Use at an assay dependent dilution. 2 µl of this antibody will immunoprecpitate 65-80% dopamine recombinant D3 receptor protein from COS1 cells.


  • Function
    This is one of the five types (D1 to D5) of receptors for dopamine. The activity of this receptor is mediated by G proteins which inhibit adenylyl cyclase. Promotes cell proliferation.
  • Tissue specificity
  • Involvement in disease
    Genetic variation in DRD3 is associated with essential tremor hereditary type 1 (ETM1) [MIM:190300]. ETM1 is the most common movement disorder. The main feature is postural tremor of the arms. Head, legs, trunk, voice, jaw, and facial muscles also may be involved. The condition can be aggravated by emotions, hunger, fatigue and temperature extremes, and may cause a functional disability or even incapacitation. Inheritance is autosomal dominant.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Post-translational
    Phosphorylated by GRK4 (GRK4-alpha and GRK4-gamma).
  • Cellular localization
    Cell membrane. Both membrane-bound and scattered in the cytoplasm during basal conditions. Receptor stimulation results in the rapid internalization and sequestration of the receptors at the perinuclear area (5 and 15 minutes), followed by the dispersal of the receptors to the membrane (30 minutes). DRD3 and GRK4 co-localize in lipid rafts of renal proximal tubule cells.

  • Anti-Dopamine Receptor D3 antibody (ab42114) at 1/750 dilution + PC-D3R sample

    Predicted band size: 50 kDa
    Observed band size: 50 kDa

  • ICC/IF image of ab42114 stained PC12 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 (ab42114, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 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.
