Dopamine D1 receptor

Organism

Human 1, 2; Rat 3

Functional implication

Agonist treatment causes the receptor shift to caveolar plasma membrane 1, 2, 3; Caveolin-2 antisense reduces cAMP accumulation 1; Caveolin-1 binding motif mutation and MβCD treatment abolish receptor internalization 2

Methods used to detect raft association

Detergent-free 1, 2, 3; Confocal microscopy 1; Bioluminescence Resonance Energy Transfer (BRET) 2

Mechanism of raft association

Interaction with caveolin 1; Bound caveolin-1 2

Caveolin-binding motif

Yes 2

Cell type

HEK-293 1; Proximal tubular cells 1,3; COS-7 cells 2

Species

Human 1, 2; Monkey 2; Rat 3

Receptor expression

Stable transfection 1;  COS-7: Transient transfection 2; Endogenous 3
