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.

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.

What acts on it

  1. Glycine slowed G-alpha-o deactivation only when GPR158 was coexpressed with RGS7/G-beta5, supporting inhibition of the complex's GTPase-accelerating activity.

Where it participates (unsigned role)

  1. Added glycine reduced cAMP in GPR158-expressing U87 and HEK293 assays; coexpression of RGS7/G-beta5 strengthened the response.
