Receptors are proteins that play a crucial role in cell signaling, acting as the initial point of contact for various signaling molecules. They are classified into several types based on the nature of the signaling molecule they bind to and the mechanism of signal transduction. Receptors can be found on the surface of cells or within the cell membrane, and their activation leads to a cascade of intracellular events that ultimately result in a cellular response.
G-protein-coupled receptors (GPCRs) are one of the largest families of receptors, comprising over 800 members. They
Ion channel receptors, such as nicotinic acetylcholine receptors, are another type of receptor that directly allow
Receptors are also involved in the regulation of gene expression. Nuclear receptors, for example, are ligand-activated
In summary, receptors are essential components of cell signaling, playing a vital role in the regulation of
