GC-globulin: a first-in-class extracellular allosteric modulator of GLP-1 receptor signalling

GC-globulin is a naturally occurring extracellular allosteric modulator that enhances GLP-1 receptor signalling. Preclinical studies demonstrate synergistic glucose lowering, reduced food intake and weight loss with GLP-1 receptor agonists, supporting enhanced efficacy at lower agonist doses.

This first-in-class platform enables extracellular modulation of GPCR signalling across multiple receptor families.

Applications: Type 2 diabetes, obesity, MASLD, neurodegenerative disease

Features Benefits
First endogenous extracellular modulator of GLP-1R Novel mechanism with strong differentiation from existing GLP-1 therapies
Synergistic activity with GLP-1 receptor agonists Potential to improve efficacy while reducing agonist dose
Compatible with existing GLP-1 drug class Applicable to marketed and next-generation incretin therapeutics
Cryo-EM and mechanistic studies identify a defined extracellular binding interface Enables rational optimisation and engineering of next-generation molecules
Broad therapeutic potential across metabolic disease Opportunities beyond diabetes, including obesity, MASLD and neurodegeneration
