Abstract

Dopamine D(2) and D(4) receptors partially codistribute in the dorsal striatum and appear to play a fundamental role in complex behaviors and motor function. The discovery of D(2)R-D(4.)(x)R (D(4.2)R, D(4.4)R or D(4.7)R) heteromers has been made in cellular models using co-immunoprecipitation, in situ Proximity Ligation Assays and BRET(1) techniques with the D(2)R and D(4.7)R receptors being the least effective in forming heteromers. Allosteric receptor-receptor interactions in D(2)R-D(4.2)R and D(2)R-D(4.4) R heteromers were observed using the MAPK assays indicating the existence of an enhancing allosteric receptor-receptor interaction in the corresponding heteromers between the two orthosteric binding sites. The bioinformatic predictions suggest the existence of a basic set of common triplets (ALQ and LRA) in the two participating receptors that may contribute to the receptor-receptor interaction interfaces.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The 7 R DRD4 allele reduces in-vitro DRD4 expression and is less likely to form heterodimers with the dopamine D2 receptor, while the 4 R allele appears less responsive to quinpirole-mediated DRD4 upregulation.

    “The 7 R has been shown to reduce in-vitro DRD4 expression [73] and to be less likely to form heterodimers with the dopamine D2 receptor [76], while the 4 R allele appears to be less responsive to quinpirole-mediated DRD4 upregulation [74].”

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.
