Abstract

Dopamine D 4 receptors (D 4 Rs) are G protein‐coupled receptors that play a role in attention and cognition. In the present study, we investigated the dimerization properties of this receptor. Western blot analysis of the human D 4.2 R, D 4.4 R and D 4.7 R revealed the presence of higher molecular weight immunoreactive bands, which might indicate the formation of receptor dimers and multimers. Homo‐ and heterodimerization of the receptors was confirmed by co‐immunoprecipitation and bioluminescence resonance energy transfer studies. Although dimerization of a large number of G protein‐coupled receptors has been described, the functional importance often remains to be elucidated. Folding efficiency is rate‐limiting for D 4 R biogenesis and quality control in the endoplasmic reticulum plays an important role for D 4 R maturation. Co‐immunoprecipitation and immunofluorescence microscopy studies using wild‐type and a nonfunctional D 4.4 R folding mutant show that oligomerization occurs in the endoplasmic reticulum and that this plays a role in the biogenesis and cell surface targeting of the D 4 R. The different polymorphic repeat variants of the D 4 R display differential sensitivity to the chaperone effect. In the present study, we show that this is also reflected by bioluminescence resonance energy transfer saturation assays, suggesting that the polymorphic repeat variants have different relative affinities to form homo‐ and heterodimers. In summary, we conclude that D 4 Rs form oligomers with different affinities and that dimerization plays a role in receptor biogenesis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
