Cell Signaling GPCR Pathways - I

Inactive Gα subunit is bound to

GDP, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.

Cell Signaling Fundamental Principles

Binding affinity is inversely proportional to

The equilibrium dissociation constant Kd is the ratio of the dissociation rate constant to the association rate constant. A higher numerical value of Kd therefore indicates that dissociation is favored relative to association, resulting in weaker net binding. Affinity is consequently the reciprocal of Kd. This inverse relationship is fundamental to the quantitative interpretation of all reversible ligand–receptor interactions.
