Here

The parathyroid hormone works on Gs G protein which then leads to increased levels of cAMP (as second messenger).

To reinforce the concept, remember that Pseudohypoparathyroidism is caused by a fault in the G protein receptor signaling pathway and it has decreased urinary cAMP levels

I'll tell where did you read it. You read it in Kaplan Qbank :rolleyes:
