WebVideo Lecture. G-protein-coupled receptors (GPCRs), also called metabotropic receptors, are membrane-bound proteins that activate G-proteins after binding neurotransmitters. Like ionotropic receptors, metabotropic receptors are primarily located along the dendrites or cell body, but they can be present anywhere along the neuron if there is a ... WebOct 23, 2024 · For example, G protein-coupled receptors (GPCRs) are involved in a wide variety of cellular processes, including cell proliferation, metabolism, and differentiation. Ion channel-linked receptors, on the other hand, are typically found in the cell membrane and are responsible for mediating ion channel activity.
