Where this comes from

Abstract

Partial agonism describes the relative efficacy of a drug compared to one that produces a greater response in a particular system; the designation is dependent upon the comparator and the system. In this issue of Cell, Huang et al. describe biophysical approaches to define the signature of GPCR partial agonists, providing direct measures of varying intrinsic efficacy.
