proximal tubules
We conclude that decrease in D(1)-like dopamine receptor binding       sites and diminished activation of G proteins, resulting perhaps from defective       coupling, led to the reduced inhibition by dopamine of Na,K-ATPase activity in       the proximal tubules of obese Zucker rats.
