Webb1 apr. 2024 · The neuromodulator dopamine plays a key role in motivation, reward-related learning, and normal motor function. The different affinity of striatal D1 and D2 dopamine receptor types has been argued to constrain the D1 and D2 signaling pathways to phasic and tonic dopamine signals, respectively. However, this view assumes that dopamine … Webb13 apr. 2024 · We show that receptor overexpression results in increased membrane dynamics, leading to an apparent decrease in binding on-rate and consequently in higher, up to 10 times, calculated K d. Thus, measurements of binding affinities of WNT-3A to FZD 7 obtained in overexpressed cells are suboptimal compared to the measurements from …
