<prompt> If there is a Gs alfa subunit gain-of-function mutation, this results in:Decreased cAMPDecreased IP3Increased GTPase activityIncreased cAMP  <response>: D i.e. Increased cAMPGs-a subunit gain would cause increased adenyl cyclase level - ultimately resulting in increased c-AMP levelQ, because adenyl cyclase conves ATP to c-AMP.
