GPCR Antibodies Overview

GPCR Antibodies target G protein–coupled receptors (GPCRs), the largest and most diverse family of membrane receptors in the human genome. GPCRs transduce extracellular signals—such as hormones, neurotransmitters, and sensory stimuli—into intracellular responses by coupling to heterotrimeric G proteins. These receptors regulate virtually every physiological process, including vision, taste, smell, cardiovascular regulation, immune function, and neurotransmission.

Because GPCRs are involved in so many critical pathways, they represent the target of more than one-third of all approved drugs. Dysregulation of GPCR signaling contributes to cardiovascular disease, neurological disorders, cancer, inflammation, and metabolic syndromes. The GPCR Antibodies portfolio provides researchers with essential tools for detecting, localizing, and quantifying GPCRs in tissues, cells, and model systems.
