Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space. The extracellular molecules may be hormones, neurotrans… WebApr 14, 2024 · Abstract.

WebJan 17, 2024 · Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored, or integral proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal. Ligands that interact with … Here’s one way to think about it: A receptor is like a lock, while the substance binding to it is the key. Thus, only substances that fit the “lock” can bind to a particular receptor. Substances binding to receptors on cells can tell the cell to: 1.
