Heterotrimeric Gs protein
Heterotrimeric Gs protein. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
Cannabinoid receptors coupled to both Gs and Gi and could consequently stimulate or inhibit cAMP formation, with an identical rank order of agonist potency in both assays but markedly different intrinsic activities, anandamide and CP-55,940 being much less efficacious at stimulating cAMP than at inhibiting it, and forskolin enhancing the potency of some agonists a hundred-fold while not affecting others.
