WebApr 13, 2024 · Individual neurons or muscle cells express many G protein coupled receptors (GPCRs) for neurotransmitters and neuropeptides, yet it remains unclear how cells integrate multiple GPCR signals that all must activate the same few G proteins. We analyzed this issue in the C. elegans egg-laying system, where multiple GPCRS on muscle cells promote … WebSignaling cascades initiated by cell surface receptors change cell’s activity or set off transcription factors to activate transcription and translation of new proteins. Receptors work by forces of physical attraction between a ligand and a ligand binding domain of the receptor also known as the “key and lock” strategy.
