    G-protein coupled receptors: Introduction

    G-protein coupled receptors (GPCRs) are integral membrane proteins that are involved in cell signaling pathways. They are found in almost all eukaryotic cells and are responsible for mediating the effects of various hormones, neurotransmitters, and other extracellular signals on the cell. GPCRs are the targets of many drugs and are important for understanding the mechanisms of drug action.

    GPCR Signaling

    GPCRs are activated when they bind to their cognate ligands, which can be hormones, neurotransmitters, or other extracellular signals. Upon ligand binding, the GPCR undergoes a conformational change, which results in the activation of a G-protein. This G-protein then activates various downstream signaling pathways, resulting in a cellular response.

    GPCR Structure

    GPCRs are transmembrane proteins that consist of seven transmembrane helices connected by three extracellular and three intracellular loops. The extracellular loops contain the ligand-binding sites, while the intracellular loops contain the G-protein-binding sites.

    Antibodies

    Antibodies are proteins produced by the immune system to recognize and bind to specific antigens. They can be used to detect and quantify GPCRs in cells and tissues. ProteoGenix provides a wide range of antibodies specific to GPCRs, including those that can be used for immunoprecipitation, western blotting, immunofluorescence, and ELISA.
