Receptor (biochemistry) - Wikipedia

https://en.wikipedia.org/wiki/Receptor_(biochemistry)
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. [1] These signals are typically chemical messengers [nb 1] which bind to a receptor and produce physiological responses such as change in the electrical activity of a cell.

Physiology, Cellular Receptor - StatPearls - NCBI Bookshelf

https://www.ncbi.nlm.nih.gov/books/NBK554403/
Cellular receptors are proteins either inside a cell or on its surface that receive a signal. This is a chemical signal in normal physiology where a protein ligand binds a protein receptor. The ligand is a chemical messenger released by 1 cell to signal itself or a different cell. The binding results in a cellular effect, which manifests as any number of changes in that cell, including

https://www.ncbi.nlm.nih.gov/books/NBK9866/
The cloning of the first receptor for a member of the TGF-β family in 1991 revealed that it is the prototype of a unique receptor family with a cytosolic protein-serine/threonine kinase domain. Since then, receptors for additional TGF-β family members have similarly been found to be protein-serine/threonine kinases.

The size and extent of each of these domains vary widely, depending on the type of receptor. Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.

Human nervous system - Receptors, Signals, Pathways | Britannica

https://www.britannica.com/science/human-nervous-system/Receptors
Human nervous system - Receptors, Signals, Pathways: Receptors are biological transducers that convert energy from both external and internal environments into electrical impulses. They may be massed together to form a sense organ, such as the eye or ear, or they may be scattered, as are those of the skin and viscera. Receptors are connected to the central nervous system by afferent nerve fibers.

https://bio.libretexts.org/Bookshelves/Introductory_and_General_Biology/Principles_of_Biology/01%3A_Chapter_1/07%3A_Cell_Communication/7.02%3A_Types_of_Receptors
The ligand-receptor complex moves into the nucleus, then binds to specific regions of the DNA and promotes the production of mRNA from specific genes (Figure \(\PageIndex{2}\)). Internal receptors can directly influence gene expression (how much of a specific protein is produced from a gene) without having to pass the signal on to other

Receptor | Nerve Endings, Signaling & Sensory Perception

https://www.britannica.com/science/receptor-nerve-ending
receptor, molecule, generally a protein, that receives signals for a cell. Small molecules, such as hormones outside the cell or second messengers inside the cell, bind tightly and specifically to their receptors. Binding is a critical element in effecting a cellular response to a signal and is influenced by a cell's ability to express only

Several types of cell-surface receptors contain or are associated with kinase activities that respond to the binding of a ligand. Perhaps best understood are receptors with intrinsic protein tyrosine kinase domains. This receptor tyrosine kinase (RTK) family has more than 50 human members (Lemmon and Schlessinger 2010). RTKs have important

14.2: Receptors and Ligands. A protein that happens to bind something is not necessarily a receptor. A receptor is defined as a protein that binds to an extracellular ligand, and then undergoes a conformational or biochemical shift in such a way that it initiates a chain of intracellular events by which the cell reacts to the extracellular signal.

Receptor Types - Neuroscience - NCBI Bookshelf

https://www.ncbi.nlm.nih.gov/books/NBK10989/
Channel-linked receptors (also called ligand-gated ion channels) have the receptor and transducing functions as part of the same protein molecule. Interaction of the chemical signal with the binding site of the receptor causes the opening or closing of an ion channel pore in another part of the same molecule. The resulting ion flux changes the membrane potential of the target cell and, in some

Drug-Receptor Interactions - Clinical Pharmacology - MSD Manual

https://www.msdmanuals.com/professional/clinical-pharmacology/pharmacodynamics/drug%E2%80%93receptor-interactions
A drug's ability to affect a given receptor is related to the drug's affinity (probability of the drug occupying a receptor at any given instant) and intrinsic efficacy (intrinsic activity—degree to which a ligand activates receptors and leads to cellular response). A drug's affinity and activity are determined by its chemical structure.

Physiology, Sensory Receptors - StatPearls - NCBI Bookshelf

https://www.ncbi.nlm.nih.gov/books/NBK539861/
Adaptation is a common property of all sensory receptors. As a stimulus constantly excites the receptor, there will be a decrease in the rate of action potentials. Although receptors can adapt to a constant, unchanging stimulus, if there is a change, whether loss of the stimulus or change in intensity, the receptor is able to respond.
