How do cells use signal molecules
WebSignals (a.k.a. ligands) and receptors come in many varieties, and binding can trigger a wide range of signal relay cascades inside the cell, from short and simple to long and complex. Despite these differences, signaling … WebJun 8, 2024 · Signaling molecules bind to the extracellular domain of two nearby tyrosine kinase receptors, which then dimerize. Phosphates are then added to tyrosine residues on the intracellular domain of the receptors and can then transmit the signal to the next messenger within the cytoplasm. Key Points
